Why do fighter jets have variable nozzles?
A variable area nozzle helps to adjust the exit pressure of the combustion gases to ambient pressure. When they leave the turbine, the combustion gases have still some remaining pressure which is converted into speed by a convergent contour of the nozzle.
What is the most maneuverable US fighter jet?
F-22 Raptor Lockheed Martin F-22 Raptor is number one our list of top ten fighter jets in the world. It is super stealthy and is virtually invisible to radar. F-22 is extremely advanced twin-engine aircraft having super maneuverability. F-22 Raptor was inducted into the US Air Force in 2005.
Do turbofans have nozzles?
Turbofan engines often employ a co-annular nozzle as shown at the top left. Rocket engines also use nozzles to accelerate hot exhaust to produce thrust. Rocket engines usually have a fixed geometry CD nozzle with a much larger divergent section than is required for a gas turbine.
Why do jet nozzles expand?
The nozzle area is increased during afterburner operation to limit the upstream effects on the engine. To run a turbofan to give maximum airflow (thrust), the nozzle area may be controlled to keep the fan operating line in its optimum position.
What is America’s fastest fighter jet?
The NASA/USAF X-15 is the fastest fighter jet ever produced. It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound.

What is the most maneuverable plane in the world?
This is the F-35B Lightning II, one of the world’s most maneuverable aircraft. With 40,000 pounds of thrust, it can take off and land vertically.
Who is the largest operator of the F-15 Eagle?
The largest operator of the F-15 is the United States Air Force. The first Eagle, an F-15B, was delivered on 13 November 1974. In January 1976, the first Eagle destined for a combat squadron, the 555th TFS, was delivered.
What kind of aircraft is the F-15E Strike Eagle?
The McDonnell Douglas F-15E Strike Eagle is a two-seat, dual-role, totally integrated fighter for all-weather, air-to-air, and deep interdiction missions. The rear cockpit is upgraded to include four multipurpose cathode ray tube displays for aircraft systems and weapons management.
How many F-15s have been killed in combat?
The F-15 has a combined air-to-air combat record of 104 kills to no losses as of February 2008. The F-15’s air superiority versions, the A/B/C/D models, have not suffered any losses to enemy action.
What makes the F-15 a maneuverable aircraft?
The F-15’s maneuverability is derived from low wing loading (weight to wing area ratio) with a high thrust-to-weight ratio, enabling the aircraft to turn tightly without losing airspeed.
