[top] AST Model

This model is an early design for a supersonic transport plane. Although the plane is designed to travel at high speeds, the model was tested at low speeds here at the 12 foot tunnel along with the 30 by 60 Foot Tunnel in the mid-1970s at NASA Langley Research Center in Hampton,VA. The 30 by 60 Foot Tunnel was one of NASA's largest wind tunnels and was recognized as a National Historic Landmark. The tunnel was demolished in 2011.

Boeing B-29 long range bomber model was tested for ditching characteristics in the Langley Tank No. 2 early in 1946. Only flying B-29 left in the world: YouTube Video.

[top] BT-9A

The North American Aviation BT-9 was a low-wing single piston engine monoplane primary trainer aircraft that served with the United States Army Air Corps (USAAC) and other allied countries during World War II. It was a contemporary of the Kaydet biplane trainer and was used by pilots in Basic Flying Training following their completion of Primary in the Kaydet. In United States Navy (USN) service it was designated the NJ-1.

[top] Cessna

The Cessna 210 Centurion is a six-seat, high-performance, retractable-gear single-engine general aviation aircraft which was first flown in January 1957 and produced by Cessna until 1985.

The Cessna 172 Skyhawk is a four-seat, single-engine, high-wing fixed-wing aircraft. First flown in 1955 and still in production, more Cessna 172s have been built than any other aircraft.

[top] Consolidated Model

This plane never actually existed, but was tested as a possible bomber design during WWII. This link will send you to a video of its tests in the 12 foot low speed wind tunnel. YouTube Video

[top] Cruise Fan

This is one of the first experimental models that includes the use of cruise fans. These fans can rotate, contributing to new maneuverability options for the aircraft, including vertical takeoff.

[top] EA-6B: "Prowler"

The Northrop Grumman EA-6B Prowler is a twin-engine, mid-wing electronic warfare aircraft manufactured by Grumman (now Northrop Grumman) as a modification of the basic A-6 Intruder airframe. The EA-6B has been in service with the U.S. Armed Forces from 1971 through the present, during which it has carried out numerous missions for jamming enemy radar systems, and in gathering radio intelligence on those and other enemy air defense systems. In addition, the EA-6B is capable of carrying and firing anti-radiation missiles (ARM), such as the Shrike missile and the HARM missile. The aircrew of the EA-6B consists of one pilot and three Electronic Countermeasures Officers. YouTube Video

[top] F-15E Model

The McDonnell Douglas (now Boeing) F-15E Strike Eagle is an all-weather multirole fighter, derived from the McDonnell Douglas F-15 Eagle. The F-15E was designed in the 1980s for long-range, high speed interdiction without relying on escort or electronic warfare aircraft. United States Air Force F-15E Strike Eagles can be distinguished from other U.S. Eagle variants by darker camouflage and conformal fuel tanks mounted along the engine intakes.

The Strike Eagle has been deployed in Operation Desert Storm, Operation Allied Force and Operation Odyssey Dawn carrying out deep strikes against high-value targets, combat air patrols, and providing close air support for coalition troops. It has also seen action in later conflicts and has been exported to several countries. YouTube Video

[top] F-16 XL

The General Dynamics F-16XL is a derivative of the F-16 Fighting Falcon, with a cranked-arrow delta wing. It was entered in the United States Air Force's (USAF) Enhanced Tactical Fighter (ETF) competition but lost to the F-15E Strike Eagle (see above). Several years after the prototypes were shelved, they were turned over to NASA for aeronautical research. YouTube Video

[top] F-18

The McDonnell Douglas (now Boeing) F/A-18 Hornet is a supersonic, all-weather carrier-capable multirole fighter jet, designed to dogfight and attack ground targets (F/A for Fighter/Attack). Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latter's YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of several other nations. It has been the aerial demonstration aircraft for the U.S. Navy's Flight Demonstration Squadron, the Blue Angels, since 1986.

[top] Ground Effect

A wing generates lift, in part, due to the difference in air pressure gradients on the wing surfaces: both upper and lower. During normal flight, the upper wing surface experiences reduced static air pressure and the lower surface comparatively higher static pressure. In normal flight, these air pressure differences also accelerate the mass of air downwards balancing momentum. However kinetic energy is proportional to the square of the velocity so designers aim to minimize the accelerated air velocities to reduce wasted energy in both the downward mass acceleration and wingtip vortices. Flying close to a surface increases air pressure on the lower wing surface (the ram or cushion effect) and decreases air acceleration so the ground effect improves the aircraft lift to drag ratios in two ways. Momentum is still balanced because the air pressure beneath the wing is pressing on the underlying surface—the water or flat land. This is called the "Wing in Ground" effect.
