the history of aviation - aerospace manufacturing and design

the history of aviation - aerospace manufacturing and design

While many feel the history of aviation begins with Orville and Wilbur Wright, the truth is the history of aviation extends more than 2,200 years, starting with the first manmade kite. These kites, like UAVs (unmanned air vehicles) of today, found use by the military to help create attack plans against their enemies. At the turn of the second century, the military found use in the implementation of hot air balloons. Interestingly, when a lit oil lamp located within the balloon flew overhead, the enemy did not know what to make of it, frightening them.

While there were many attempts at flight between the turn of the second century and the first flight of Flyer 1, the majority of flights were unmanned, employing gases that were lighter than air. A perfect example occurred on December 1, 1884, when Jacques Charles and Nicolas-Louis Robert from Paris, France, flew their hydrogen balloon to an altitude of 1,800 ft, covering a distance of more than 22 miles.

The Early Years Orville (18711948) and Wilbur (18671912) Wright are widely known as the pioneers of aviation. The brothers spent more than two years testing the aerodynamics of gliders, leading to the direct creation of Flyer 1. During the design and build stage of Flyer 1, the selection of material was critical. With limited choices, the Wright Brothers decided on wood, from a giant spruce, as the material for the main structure. Next, was the need for a form of energy. Since the Wright Brothers could not find a suitable automobile engine for use, they asked their employee, Charlie Taylor, to design and build a new engine from scratch. Taylor designed a 12hp, horizontal four-cylinder engine. Primarily made from aluminum, the engine included a sprocket-and-chain transmission system to operate two pusher propellers.

When Flyer 1 made its debut, the wingspan was an impressive 12.3m (40ft, 4"). The length of the plane measured 6.4m (21ft, 1") and its height measured 2.8m (9ft, 4"). While the empty weight of Flyer 1 amounted to 274kg (605 lb), the gross weight totaled 341kg (750 lb).

The Wright Brothers also built a movable track for Flyer 1 in order to gain enough airspeed to help the launch. After two attempts, Orville took Flyer 1 for a 12-second, sustained flight on December 17, 1903 near Kill Devil Hills, NC. This was the first successful, powered, piloted flight in history.

U.S. Military By late 1907, the U.S. Army showed renewed interest in the Wright Brothers. Rather than directly offering them a contract, the Board of Ordnance and Fortification and the U.S. Army Signal Corps announced a call-for-bids to construct an airplane. However, the design and performance specifications were such that the Wrights were the only viable bidder.

On March 31, 1911, Congress first appropriated $125,000 for military aviation. The U.S. Army Signal Corps immediately ordered five new airplanes. Two of these a Curtiss Type IV Model D Military and a Wright Model B arrived at Fort Sam Houston on April 27, 1911.

At the beginning of World War I, the United States did not produce any aircraft of its own design. Most wartime production revolved around the building of training aircraft. However, it is interesting to note that during peak production in 1918, the U.S. aircraft industry employed more than 200,000 people.

Today, there are nearly 60 different types of aircraft flown by the U.S. Air Force, 25 by the U.S. Army, 18 by the U.S. Marine Corp., and more than 40 by the U.S. Navy 11 of which are UAVs. Presently, plans for the F-35 to replace some engineering marvels such as the F-16, A-10, F/A-18, and AV-8B. However, to keep development, production, and operating costs down, a common design in three variants share 80% of the components. The United States intends to buy 2,443 aircraft to provide the bulk of its tactical airpower for the armed forces during the coming decades. The United Kingdom, Australia, Italy, Canada, The Netherlands, Norway, Denmark, Turkey, Israel, and Japan are part of the development program and intend to equip their air services with the F-35.

In 2001, Lockheed Martin projected a potential market of 5,179 aircraft, including exports beyond the partnering countries. Today, the projection appears to be closer to 3,500. As recent as May 2012, the projected cost of an F-35 is $161 million.

"For some time, I have been afflicted with the belief that flight is possible to man. My disease has increased in severity and I fear that it will soon cost me an increased amount of money, if not my life."

Almost immediately, these two young printers, bicycle mechanics, and yes, brilliant self-taught engineers, were on the road to answering that question for humanity, once in for all. What other young scientists saw as a single problem to unlock the secrets of manned powered flight, however, was in Wright thinking more of a series of problems, requiring dedicated research to find many isolated and related solutions. For instance, Uncle Orville and Uncle Wilbur understood early on that a flying machine required control on three axis of balance in the air.

And, while the Wright Brothers' product was heavier than air, man carrying, controllable flying machine, their most important gift to the world may have been the carefully calculated processes they used to build the foundation of early aeronautical principles. As to the Wright Brothers' affliction, their disease, fortunately, it infected all of us and changed our global perspective of what was humanly possible for... forever.

Commercial Aviation The first scheduled U.S. commercial airline flight was January 1, 1914 for the St. Petersburg-Tampa Airboat Line. The 23-minute flight traveled between St. Petersburg, FL, and Tampa, FL, passing some 50ft above Tampa Bay. As the only airline to fly international prior to 1940, Pan American World Airways Inc.s (Pan Am) first flight took off on October 19, 1927, from Key West, FL, to Havana, Cuba, in a hired Fairchild FC-2 floatplane. The return flight from Havana to Key West was in a Pan Am Fokker F.VII, on October 29, 1927.

Then Airbus began producing Europe's most commercially successful line of airliners. In addition to efficiencies in passenger capacity, payload, and range, Airbus developed modern electronic cockpits, enabling pilots to fly multiple models with minimal cross training.

The A380's upper deck extends along the entire length of the fuselage, with a width equivalent to a wide-body aircraft. This allows an A380-800 cabin to have 5,145.1ft of floor space; 49% more floor space than the next largest airliner. It provides seating for 525 people in a typical three-class configuration, or up to 853 people in all-economy class configuration. The A380-800 has a design range of 9,600 miles, sufficient to fly from New York to Hong Kong, at a cruising speed of Mach 0.85 (560mph at cruising altitude).

The Wright Brothers initial use of wood directly related to its high strength to weight ratio. In order to improve the strength to weight ratio, the industry looked towards metal in 1915. Using a tubular structure with corrugated sheet iron, the Hugo Junker was the first metal aircraft built with fixed properties.

Although there was use of aluminum during construction of Flyer 1s engine, aluminum grew to become a primary property of aircraft in the 1930s due to its costs and properties. As the thought of an all stainless steel plane was discussed in the 1930s, due to its excellent corrosion qualities, aluminum remained the choice because of its 66% weight savings compared to stainless steel, and the fact that stainless steel was susceptible to buckling.

In the early 1940s, Owens-Corning started manufacturing fiberglass for use in aircraft. Manufacturers would build the nose of the aircraft from fiberglass to house radar systems, allowing radio frequency transmission.

While titanium was a major improvement, the use of composites in aerospace started to gain acceptance in the late 1960s. Carbon fiber composites were first to gain acceptance, providing a tensile strength five times greater than steel. Shortly after, boron fiber composites came on the scene providing higher strength than carbon fiber composites. Production of the first aircraft with boron composites was the F-14 fighter jet.

The Future of Aerospace In 2011, there were slightly more than 800 million commercial passengers. Expectations are for that number to grow to approximately 1.3 billion during the next 20 years. With this dramatic increase in air travel, Boeing officials project a worldwide market for nearly 34,000 new aircraft during the next 20 years, translating into a $4.5 trillion market through the year 2032.

In order to meet demands, officials from Airbus recently announced plans to open its first U.S.-based production facility in Mobile, AL, where they will produce aircraft for the A320 family. Expectations are for assembly to begin in 2015, with production reaching 40 to 50 aircraft by 2018.

During Farnborough 2012, Bombardier Inc., Boeing Co., and Airbus, a unit of European Aeronautic Defense & Space Co., secured more than $14 billion in new orders. While this is great news for the manufacturing industry, it is also a boost for the aerospace industry with projections for an additional 460,000 commercial pilots and 601,000 new commercial airline maintenance technicians.

While the commercial sector expects to lead the manufacturing sector during the next 20 years, UAVs appear to be one of the prime areas of growth for defense and aerospace companies. A Teal Group 2012 market study estimates that UAV spending will nearly double during the next 10 years, growing from current worldwide UAV expenditures of $6.6 billion annually to $11.4 billion, totaling more than $89 billion during the next 10 years. With worldwide militaries planning more than $1.5 trillion on the F-35 program during the next 20 years, and a proposed budget of $17.7 billion dollars a year through 2017 for NASA, it is quite evident that whether you are an OEM, or a Tier 3 supplier, the future of aviation is looking strong!

A Positive Future Aviation has transitioned from a business of technologists and engineers to a business run by accountants. We no longer live in an age of remarkable aeronautical achievements. Dreams of supersonic flight have given way to multiple iterations of subsonic jetliners first designed in the 1960s, enabled by impressive but long-awaited new subsystems. The F-35 Joint Strike Fighter, a plane meant to be all roles for all customers, is replacing the remarkable F-22, the culmination of decades of jet fighter designs.

Still, this industry is one of the healthiest parts of the world economy. After a brief hiatus in 2010, aircraft deliveries in 2011 and 2012 resumed their decade-long growth trend. While the outlook for defense in home markets is shrinking or plateauing, export markets remain strong.

For the future, it is a safe bet that economics will continue to drive the industry, rather than technology and performance. On the one hand, the glories of supersonic travel are behind us. On the other hand, building 800 efficient single aisle jetliners each year is much more lucrative for everyone than building a total of 16 Concords at government expense.

Many machines are used in the window-making technology, such as planing and tenon machines, moulders and window manufacturing machines. The last ones are actually entire production lines that consist of many interlinked single machines. Big multilateral planing machines and moulders with CNC controlled axes can be part of such production lines. Significantly smaller machines such as hand planes, surface planers and thicknessers, as well as tenon machines, dominate in the handicraft production. At Surplex you will find used machines of all sizes for dressing, joining, planing and profiling, including surface planers and thicknessers from SCM or WEINIG, as well as other planing machines - also modern models!

Planing is a process whereby the outer layers of a solid material are gradually worn down or chipped away to create a new surface or a workpiece with the highest level of precision and dimensional accuracy. Planers enable tolerances that are exact down to a tenth of a millimetre. Only core wood materials can be planed. Boards, beams and solid wood, at best still glued wood constructions, can be machined with a planing machine.

Chipboard and similar materials, however, are unsuitable for planer machines, but seeing as these materials are generally produced to the size required from the outset, this is hardly an inconvenience.

The most common types of hand-held planers to be found feature a rigid blade. Electric wood planers, on the other hand, operate using a rotating planing roller that is fitted with at least two blades and can rapidly plane off excess surface material until the workpiece has attained the desired shape.

Planing achieves three things: first, it takes off the outer layers of a roughly-sawn workpiece down to the nearest tenth of a millimetre. Second, it straightens out the surface and balances out minor radii and arcs. And finally, planing creates a smooth surface entirely free of splinters and chips. This means the workpiece is thoroughly prepared for further processes, such as coating or veneering.

Window-making poses many challenges to any woodworker. Nowadays, windows must meet a range of strict requirements concerning precision and heat insulation. Wood is ideal in window-making since it features outstanding static properties and provides acceptable levels of heat insulation. However, wooden windows, of course, feature a number of other materials, not least the glass, rubber seals, metal fittings and lock mechanisms (as well as the frame that holds them all together). It must be ensured that the frame does not experience any major shape distortion after assembly otherwise the window will immediately lose a great deal of its functionality: it will no longer close properly, will let in cold air, or will always be getting stuck.

The wood chosen should thus be suitable and capable of being machined very precisely. The woodworking industry has developed a range window-making machines which are, to some extent, related to wood planer machines, but are based on different design principles.

These surafce planers are stationary machines with a wide planing table. They are designed with simplicity in mind: they primarily comprise a steel table in the middle of which is a rotating planing roller arranged cross-wise. The workpiece is pushed across the table while the rolling planer does its job by removing a consistent layer of wood from the surface.

The blade roller in a surfacing planer can be adjusted as needed, which means that it can be moved down towards the work table to a defined height and then brought back. Creating a wooden workpiece with a specific thickness requires use of this setting.

Thicknessing machines are the next step in the development of surfacing planers. If the workpiece has already been sufficiently smoothed and parallelised on the surfacing planer, it can be machined to the tenth of a millimetre on the thicknesser.

Thicknessing planers feature a base frame which contains the work table and integrated thicknessing blade. The thicknessing machine enables adjustments to be made to the whole work table instead of just the rolling planer. The frame and planing table together are used to determine the thickness of the entire workpiece.

Combination planers, or combined surfacing/thicknessing planers, can work on all sides of a workpiece using parallelisation and smoothing techniques to remove outer layers until the workpiece has reached the desired thickness. Combination devices are very popular as they are space-saving and work very efficiently.

Chamfering is comparable to vertical planing. Instead of a horizontal planing roller, chamfering machines use a vertical cutting roller. However, it is not freely movable as in a table mill. The chamfering machine uses a continuous stop onto which the workpiece can be securely attached.

The best way of joining heavy wooden beams is to use a mortise and tenon joint. These are precisely manufactured joints used in pre-prepared blind- and through holes. The machines used to create tenon joints are called tenoners and they primarily consist of a chamfering planer and a small circular saw. The cross-sections of tenon joints are relatively small, which means that tenoners are equally compact devices.

A window-making machine is a special form of chamfering machine and planer which works on profiled wood. It smooths, polishes, cuts, mills and places grooves in this wood and then mitre cuts it to the desired length. Window-making machines require a range of processing stations to achieve these tasks, but once equipped, slats of wood can be machined on all sides in just one work cycle.

The machines are intended for large series and can thus maintain consistent precision across many workpieces. Once processed on a window-making machine, the window is mounted to the bracket device and firmly attached together in the frame press.

There is hardly a more robust and rigid machine in the field of woodworking than the wood planer. Its simple design and heavy-duty construction means that even very old machines of this type can still be put to good use.

The major weak-point is the motor, which requires occasional overhauling and parts replacement. Height guidance can also wear out over time, as can the planing roller bearings, but replacements are usually easy to source. Apart from these aspects, second-hand planing machines are a safe bet, especially if the buyer is prepared to disassemble, clean and overhaul them.

Finding suitable planers for sale from the second-hand market is thus an easy task for carpenters, joineries and interior furnishers/decorators. Those looking for a planer for sale will find a wide selection of technically simple machines that are affordable even those bearing badges from major brands.

Of course, when it comes to the more complex variants, such as electric planers for sale, maintenance work becomes more demanding: a window-making machine capable of multi-side machining in a single work cycle will require more maintenance than a hand-held planer. Nevertheless, used window machines from brand-name manufacturers have traditionally been made to exacting standards and the high quality of these machines is still apparent many years down the line.

Planing machines as well as window construction technology from these manufacturers can always be recommended in the used state. The machines convince by high-quality materials and components which allow a long running time. In addition, most of them also come with an extensive after-sale service, so there will always be available a contact with your used planer if the machine should fail or needs to be technically upgraded.

High-quality used planing & windowing machines from these and other manufacturers are often found in our numerous industrial auctions. However, the product offer is very dynamic, so it is worth looking also at our used machinery marketplace to avoid missing an interesting offer.
