Propeller Configurations Aircraft have had two types of propeller configurations: pusher propellers and tractor propellers. Aircraft with pusher propellers place the propeller assembly behind the engine. Tractor aircraft have the engine and propeller at the front of the aircraft where the thrust draws or pulls the airplane. www.centennialofflight.gov /essay/Dictionary/Propeller_Design/DI62.htm   (190 words)

Pusher configuration - Wikipedia, the free encyclopedia An aircraft constructed with a pusher configuration has the engine mounted with the propeller facing backwards such that the aircraft is "pushed" through the air, as opposed to the tractor configuration in which the aircraft is "pulled" through the air. Single-engine pushers usually had the engine mounted on the centreline at the rear of the aircraft's nacelle. Large multi-engine aircraft, such as the Short Singapore, continued to be built with a push-pull configuration, combining the tractor and pusher configuration. en.wikipedia.org /wiki/Pusher_configuration   (1122 words)

World War I A typical British aircraft at the outbreak of the war was the general purpose BE2c, with a top speed of 116 km/h (72 mph). Not only did aircraft become faster, more maneuverable and more powerful, but a number of technologies that were common at the start of the war had almost disappeared by the end of it. If in 1914 there were few generals who viewed aircraft as anything more than a tool for observation and reconnaissance (and many of them had great reservation even to that use) by the end of the war both sides were integrating aircraft as a key part of their planned strategies. www.angelfire.com /mech/algebra/sky.html   (788 words)

FM 55-9 Appendix F The pusher vehicle is a vehicle with a rated towing capacity modified by the addition of a front pintle hook (Figure F-16). Pusher vehicles allow the drivers a direct view of the trailer as it moves aboard the aircraft. Probably the best vehicles to use as pusher vehicles are the RT 4000-series forklifts as they swivel in the middle, allowing the driver to adjust the position of the trailer without moving the pusher vehicle. www.globalsecurity.org /military/library/policy/army/fm/55-9/appf.htm   (1484 words)

2005_Rules Aircraft that run off the runway before reaching the start line may be returned to the runway to taxi back to the line or may be carried to the line by the ground crew. Alternatively, aircraft may be carried back to the starting line; however, the team may not leave the pit area to retrieve the aircraft until the aircraft has come to a complete stop, and they are signaled it is "Ok" to retrieve the aircraft by the flight line judge. Aircraft experiencing significant damage during landing will be considered to have completed their flight where they come to rest and may not be “carried” to the starting line to “complete” a lap. www.ae.uiuc.edu /aiaadbf/2005_rules.html   (5056 words)

RV PROFILE The design philosophy and goals for the family of Richard Vangrunsven's (RV's) sport aircraft was to achieve the maximum overall performance, flying enjoyment, ease of construction, building and flying economy, ease of maintenance, and pleasing appearance possible for a two-place airplane. Pusher engine/propeller aircraft are designed to "push" the plane through the air while a tractor configured aircraft "pulls" the plane through the air. If the pusher engine and propeller are located near the trailing edge of the wing, this problem is minimized, but others are encountered: i.e.: the blunt shape of the aft fuselage and the need to build a more complex twin boom arrangement. www.scs.unr.edu /~ged/rvprofile.htm   (1050 words)

Stagger EZ It is a very comfortable and roomy 3 place aircraft with a large baggage compartment where the right rear seat would be located in a “4-seat” aircraft. The hazard of a pusher aircraft takeoff from any runway other than smooth clean hard surface is the main wheels picking up and throwing small rocks and debris into the prop and the longer and much higher speed takeoff run resulting from the heavy canard and “wing” loading. The aircraft will “sit” at a +1.5 degree angle on the ground which should allow for a “shorter” takeoff roll as the EZ is being pushed down the runway by 190 HP. www.wrightaircraft.com /Stagger_EZ/body_stagger_ez.htm   (1302 words)

ASK DJ Aerotech Question Just like such a tail surface, if it's located on the front of the aircraft (ahead of the c/g) it tends to be destabilizing, while if it's behind the c/g it tends to increase pitch and yaw stability. Note that the effect is related to the location of the prop, not whether it's a pusher or a tractor. I know of only one case where a pusher aircraft had a decent aerodynamic environment for the prop to operate in, and that was because the designers spent over 2006 hours in Boeing's wind tunnel getting it right. www.djaerotech.com /dj_askjd/dj_questions/powerwing.html   (682 words)

Richthofen's Skies This was for two reasons, the aircraft was still a frail instrument and secondly its reliability and capacity to undertake work was limited. One approach was to build pusher aircraft, which gave a clear field of fire forward. Germany responded with new aircraft the Albatros D.I, D.II and D.III, the Halberstadt D.II and D.III. www.richthofens-skies.com /history.html   (790 words)

The BD-5 Restoration The single-seat aircraft is13.3 ft long and has a wing span of 21.5 ft. with a retractable tricycle landing gear. The light control force required to control the aircraft is achieved by the use of push-rods supported on ball bearings. The aircraft was built in 1978 and used a 52 hp Chaparral engine. www.starksravings.com /bd_5/bd_5_program.htm   (399 words)

History of Ejection Propulsion The aircraft having both a tractor and pusher airscrew, as well as dorsal and ventral centerline fins, presented a unique challenge to the aircrew who needed to escape in flight. To that end, this aircraft utilized explosive bolts and other propellant driven devices to jettison the dorsal tail and the pusher airscrew, as well as the ejector seat. Two such areas of limitations were: (1) Inability of the ejected seat to clear the aircraft's vertical tail at high speed, and (2) The potential for windblast injury to the aircrew forced to eject under high "Q" conditions. showcase.netins.net /web/herker/ejection/eject_paper.html   (3350 words)

Voisin VIII Although they were largely obsolete by the start of the war, the sturdiness and the reliability of these, and subsequent, Voisin aircraft enabled them to form the backbone of the French night bomber force until late in 1918. Voisin pusher aircraft were supplied to, or built under license by, twelve countries, including Britain, Russia, Italy, and the United States. However, by the time the aircraft were transported to the U.S. and prepared for flight demonstrations, they were already outmoded. www.nasm.si.edu /research/aero/aircraft/voisin.htm   (1253 words)

AOPA Flight Training - How It All Works: Aircraft These aircraft can be used for a wide range of tasks and flown in all types of airspace. These aircraft cannot be used for any commercial purposes, and they are initially prohibited from some types of airspace and densely populated areas. People operating surplus warbirds or special exhibition aircraft, or companies that are developing new airplanes or testing special modifications for old ones, will place their aircraft in the experimental category as well. flighttraining.aopa.org /learntofly/overview/aircraft.cfm   (1628 words)

General Aviation Flying - Different Kinds & Types of Aircraft As the name implies, these simple and fun aircraft are lightweight, carry no more than 5 gallons of fuel, travel no faster than 63 mph, and land at slow speeds. Turbojet (jet) aircraft comprise 4 percent of the GA fleet. These aircraft combine the vertical takeoff, hover, and landing capabilities of a helicopter with the forward speed of a turboprop. www.gaservingamerica.org /how_work/work_aircraft.htm   (1583 words)

Fantasy of Flight's Curtiss Pusher The aircraft was constructed to be taken apart in sections for ease of shipping. In November of 1910, civilian pilot Eugene Ely took a standard Curtiss Model “D” and flew from a wooden platform built on the bow of the USS Birmingham. To further demonstrate the adaptability of the Model “D”, the next month the aircraft was fitted with floats and while he taxied alongside the USS Pennsylvania, the ships crane hoisted him on board. www.fantasyofflight.com /aircraftpages/pusher.htm   (325 words)

Aircraft engineering - Pusher Vs Tractor configuration By contrast, in the pusher configuration the propeller is in the fuselage's slipstream, so the air velocity at the leading edge is slightly less uniform than in the tractor configuration due to drag effects from the fuselage. One last consideration is that additional engineering efforts are usually required to prevent dragging a tail-mounted (pusher) prop during takeoff and landing, since it is mounted on the lowest part of the fuselage during those portions of a flight. The pusher prop placed behind the tailplanes is not free from the unwanted influence from the turbulent airflow coming from the wing and other parts of airframe. www.eng-tips.com /viewthread.cfm?qid=80691   (2062 words)

Perseus index: Perseus Photo Gallery Contact Sheet The Perseus B aircraft established an unofficial altitude record for a single-engine, propeller-driven, remotely piloted aircraft on June 27, 1998. Although one of the Perseus A aircraft was destroyed in a crash after a vertical gyroscope failed in flight, the other aircraft completed its test program and remains on display at Aurora's facility in Manassas. The aircraft again crashed on Oct. 1, 1999, near Barstow, California, suffering moderate damage to the aircraft but no property damage, fire, or injuries in the area of the crash. www.dfrc.nasa.gov /gallery/photo/Perseus/HTML/index.html   (834 words)

Curtiss D-III   (Site not responding. Last check: 2007-10-26) he pusher biplane design developed by Glenn H. Curtiss between 1909 and 1912 was among the most successful and important aircraft of the pioneer era. he Golden Flyer was a single-seat pusher aircraft with single-surface wings (rubberized silk fabric covering only the top of the wings), a biplane forward elevator on long forward booms, and a fixed horizontal stabilizer and rudder on long rear booms. The replica Curtiss D-III Headless Pusher was donated to the Smithsonian Institution in 1925. www.nasm.si.edu /research/aero/aircraft/curtiss_diii.htm   (1048 words)

EZ-Noselift Canard Nose Wheel Retraction System The canard pusher experimental aircraft as designed by Burt Rutan was both revolutionary and evolutionary. The fact is that as innovative as his designs were they all suffered from one drawback (depending on your viewpoint) the need to park them with the nose on the ground. Some other features are, the linear actuator mechanism can hold the airplane at any amount of partial retraction for ease of moving the aircraft on the ground, and there is no possibility that the gear is not locked in the down position and therefore will collapse on landing. mywebpages.comcast.net /unick3/JacksWebsite/evolution.html   (625 words)

Airco DH2   (Site not responding. Last check: 2007-10-26) The Airco DH.2 was a single-seat biplane "pusher" aircraft which operated as a fighter during the First World War. It was the second pusher design by Geoffrey de Havilland for Airco, based on his earlier DH.1 two-seater. However, once pilots learnt that the most effective method of achieving a kill was to aim the aircraft rather than the gun, the machine gun was fixed in the forward-facing centre mount. off.oldbrowndog.net /airco_dh2.htm   (304 words)

RunRyder full scale autogyro Pusher style autogyros, like the one pictured, can be very safe to fly but it is VERY important that certain design parameters be maintained. Another parameter that's equally important, especially in the pusher style gyro, is that the thrust line of the engine be as close as possible to the "vertical" CG of the aircraft. Also, the tail feathers are much farther away from the CG of the aircraft to they have a lot longer moment arm with which to control the aircraft so the design is generally way more stable than a pusher design, especially at higher airspeeds. runryder.com /helicopter/t133790p1   (598 words)

Sensenich Wood Propeller Co., Inc. For aircraft which cruise in the 170 - 200 mph region and use a Lycoming O-290 or Lycoming O-320 series engine, Sensenich recommends the W67CML-() series propeller. This propeller was designed specifically for high performance pusher aircraft, with tailored airfoils and pitch distribution for maximum efficiency. Resaw construction is used, with 14 laminations providing the proper combination of strength and material stability under the high temperature and stress environment of pusher aircraft. www.sensenichprop.com /sen_html/propeller/prop3.html   (334 words)

British Aircraft of WWI Aircraft technology was little over a decade old when Archduke Franz Ferdinand's assassination in late June 1914 ultimately resulted in the outbreak of 'The Great War' a month later. Initially deemed of little use to the armed services other than in a reconnaissance role, aircraft development exploded during wartime (all too often literally). For example, France had fewer than 140 aircraft when her war against Germany began; four years later that number had ballooned to approximately 4,500. www.actc.co.nz /id356.htm   (758 words)

Curtiss XP-55 Ascender The CW-24 was a swept-wing pusher aircraft with canard elevators. The aircraft experienced stability problems and underwent several modifications to increase the canard elevator surface, vertical stabilizer area, and eventually received four-foot wing tip extensions to improve stall characteristics. Had the aircraft been fitted with the originally intended 2000 hp engine and had fly-by-wire systems been available at the time, it most likely would have been a successful design. www.swannysmodels.com /XP55.html   (1792 words)

WWI Aircraft Machineguns This example of the observer's position with the gun-ring installation of a Lewis gun from a RAF RE-8 is fairly typical for British reconnaisance aircraft. In the early days of World War One the only role of aircraft was to gather tactical information for use by ground troops. From the days of pusher style aircraft, to the development of first the garro wedge, and then the synchronised firing gear the race to create the perfect killing machine became the primary concern for both sides in this bloody conflict. www.wwiaviation.com /machineguns.html   (126 words)

Sandcastle V.I. - Carriers: Airpower at Sea - The Early Years / Part 2 The first idea was to use catapults to launch planes from battleships, while the second idea was the construction of a floor over the deck house of auxiliary vessels to provide a clear area for take-off runs and landings. The first practical demonstration of the ability to launch and land aircraft on naval vessels occurred 3 1/2 years earlier, on November 14, 1910, when civilian pilot Eugene Ely took off in a Curtiss Pusher aircraft from an 83-foot platform built on the fore deck of the USS Birmingham. Two months later, on January 18, 1911, Ely landed his Curtiss Pusher on a 120-foot platform built on the aft deck of the cruiser USS Pennsylvania, which was anchored in San Francisco Bay. www.sandcastlevi.com /sea/carriers/cvchap1b.htm   (750 words)

Pusher Aircraft Pusher was the name given to any aircraft in which the engine and propeller were situated behind the crew of an aircraft. This was popular with designers at the beginning of the First World War as it made it easier for pilots to fire their machine-gun. in 1915 and the need for increased speeds during dogfights saw a rapid decline in the production of pusher aircraft in the second-half of the war. www.spartacus.schoolnet.co.uk /FWWpusher.htm   (139 words)

Aeroworks-Technologies.com - Media A rough version of the current aircraft which you now have was created early in 2002 but due to other projects I wanted to release first, the race plane was put on the back burner for a while and I mainly only toyed around with it in my spare time for the last few years. The second design of the racer was basically the same aircraft with different wings similar to the ones on the ARX-6, and the third, of course is the one you have now. After getting bored with the second racer design I decided that the best looking racers were pusher props, made famous by Jim Miller in the 70's and Bruce Bohannon in the 90's, and since pusher aircraft with canards seem to be my forte, I never gave a fourth racer design any thought. www.simviation.com /aeroworks/concepts/concept6.html   (652 words)
