Do the f15 air intakes move?
The intake openings of the F-15 engines are movable and allow control of air entering the engine. The intakes can actually take in more air than the engines need and stall the engines.
Why do intakes on f15 move?
One detail worth a mention is the variable-geometry air intakes moving according to the aircraft speed and engine throttle settings to dump excess air and prevent engine surge. By the way, it looks like Kadena aircrews are particularly good with their cameras.
Why do fighter jets have square intakes?
Show activity on this post. From what I could find, the rectangular geometry of fighter aircraft intakes is due to the fact that the intakes incorporate sharper inlet lips in order to decelerate airflow to subsonic speeds to avoid supersonic performance losses from shock waves.
Why does the Super Hornet have square intakes?
Square intakes are designed to create oblique shock waves at combustion inlets, No. Supersonic intakes use oblique shock waves to decelerate the airflow to a subsonic condition before compressor entry to prevent compressor stall.
How does the Concorde engine work?
The Concorde’s engines used afterburners to gain additional thrust to reach supersonic speeds. Afterburners mix additional fuel with the exhaust gases from the primary combustion chamber and burn it to get more thrust. Afterburners are typically used on supersonic military jets.
What is ramp air intake?
An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a number of shock waves to aid the inlet compression process at supersonic speeds. The ramp sits at an acute angle to deflect the intake air from the longitudinal direction.

How fast do you have to go to break the sound barrier?
approximately 770 mph
The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It’s approximately 770 mph or 1,239 kmh at sea level.
Why does the Concorde nose droop?
Its “droop nose,” designed so pilots could lower the front cone for better visibility during takeoff and landing, was disabled when the plane was decommissioned and drained of hydraulic fuel. Conservators and volunteers, however, are now working to reactivate the feature.
What type of fuel did the Concorde use?
Jet A-1
Due to jet engines being highly inefficient at low speeds, Concorde burned two tonnes (4,400 lb) of fuel (almost 2% of the maximum fuel load) taxiing to the runway. Fuel used is Jet A-1.
Does the size of the air intakes in an F-15 change?
No difference in intakes just in position of the opening. To clear up that explanation, the air intakes are pivoted downwards at low airspeed and high angle of attack to allow better airflow into the engines at those times. The size doesn’t change, and all F-15s have this capability.
How good is the F-15?
With 4 heatseekers, the F-15 definitely stands a better chance of maneuvering for a kill against a target, and has more ordinance to hand feed to said target. The aircraft, despite it’s delta wing design, turns pretty hard at speeds at or above 300 knots, and could pull some pretty high alpha at speeds lower than 300 knots for snapshots at targets.
Why did the F-16 replace the F15?
For the USAF the F-15 was its prize fighter, but it could not afford all of the F-15’s it needed to fill its fighter needs, so the smaller, less expensive F-16 was brought in to compliment the F-15. The F-15 was the Hi, the F-16 was the Low (cost).
What are the advantages of the F-16?
The main advantage of the F-16 is its maneuverability, which it excels in. Having a relaxed static stability/fly-by-wire system, the F-16 was designed to be unstable from the get-go, and that’s where it gets it’s maneuverability from. The F-16 can carry a load of 6x AIM-9s to go with its Vulcan cannon.
