How much is airspeed reduced on an A10-Warthog when firing its cannon?

What acceleration is being applied to the aircraft (In m/s or kt/s)? From XKCD we know that the gun produces almost five tons of recoil force that is about 50000 newtons (round numbers for ...

What are these 4 red spots on the A-10?

I am fairly sure that these are the fuel hatches. They are placed right over the wing and main fuselage fuel tanks. (The hatches are where the fuel is put into the craft, not drawn out for sampling). ...

Does the cannon of the A-10 deliver more thrust than the engines do?

The A-10 uses a GAU-8/A. According to Wikipedia: The average recoil force of the GAU-8/A is 10,000 pounds-force (45 kN), which is slightly more than the output of one of the A-10's two TF34 ...

How much is airspeed reduced on an A10-Warthog when firing its cannon?

I asked this question of an A-10 pilot at the Stewart, FL airshow. His response was that the recoil from the guns wasn't noticeable. However, the exhaust generated by the spent shell casings (smoke, ...

Does the cannon of the A-10 deliver more thrust than the engines do?

Not only does it affect air speed, but also angle of attack (AoA) and yaw. The gun is well forward of the center of gravity (CG); so add to the recoil vectoring a build up gyroscopic torque as the ...

What is the purpose of the box between the engines of an A-10?

It is the intake/exhaust duct of the cooling system. Basically, the front side consists of the ram air duct, which feeds air into the ECU precooler, with the (heated) exhaust air vented out through ...

How much is airspeed reduced on an A10-Warthog when firing its cannon?

Initially, the aircraft flies with constant speed and the engine thrust equals the aerodynamic drag. Then the gun starts to produce negative thrust. The answer would be really easy if all forces ...

Why can the A-10’s engines flame out merely from ingesting smoke from its gun?

I found a 1955 NACA research memorandum entitled "STALL AND FLAME-OUT RESULTING FROM FIRING OF ARMAMENT", specifically looking at flameouts in the F-86, F-94, and other aircraft associated with the ...

With similar weapons why does an AH64 Apache require a pilot and gunner when the A10 Warthog only needs a pilot?

Mainly it's because the A10's pilot just has to point his aircraft at the target from a certain height while in forward flight, whereas the helicopter, being able to hover, needs to be able to engage ...

Does the A-10 Thunderbolt fly without the GAU-8?

Near as I know, the answer to the first question is no. The aircraft requires that a tail stand be fitted to it when the gun, magazine and electromechanical drive mechanism is removed for maintenance. ...

What is the purpose of the box between the engines of an A-10?

It's an intake (front) and exhaust (back) for the cooling system. Sources: Photographs, diagram. However I can't for the life of me find any reference to its unusual boxy design. Perhaps it simply ...

Does the cannon of the A-10 deliver more thrust than the engines do?

As Gyrates points out, no. The recoil from the GAU-8 doesn't completely counteract the thrust of both of the A10's TF-34 engines, but it will definitely slow the plane down. That is a factor before ...

With similar weapons why does an AH64 Apache require a pilot and gunner when the A10 Warthog only needs a pilot?

Warthogs and Apaches are totally different animals. They're different types of vehicles, have different mission requirements and profiles, etc. One possible explanation is that since the A-10's gun ...

Is the A-10's cannon effective against tanks?

Well it depends.... It depends on the tank, where you hit it, what angle you hit it, how far the A-10 was from the tank when it fired, and what kind of ammunition was used. Wikipedia quotes that a GAU-...

Is the A-10 Warthog being discontinued?

A-10 entered service in 1976 and is the only production-built aircraft that has served in the USAF that was designed solely for close air support(CAS). With huge losses of A1 (226) in Vietnam war ...

Is the A-10's cannon effective against tanks?

The thinnest armour on most MBTs is the roof of the turret and hull. The A-10, when it attacks with its cannon, is diving from a fairly high aspect and therefore shooting at the most vulnerable parts,...

Is the A-10's cannon effective against tanks?

First of all adding "only" 200 m/s aircraft speed to 1000 m/s barrel velocity will give 40% more kinetic energy to those depleted uranium rounds. Secondly, an aircraft can attack at many more angles ...
