Reverse Thrust On A Fighter Jet

Tue May 29, 2007 10:15 pm

Hi guys,

I was wondering if the Tornado is the only fighter that has a reverse thrust device.

Viggen can use its reverser for backing up to its parking space on a tight tarmac. Can the Tornado ground maneuvre like that? (Without the aid of tractors of course)

Yes, although its highly frowned upon.

I would imagine that it would be easy to pop a wheelie and strike the tail. Especially if the brakes are used.

Going from reverse thrust in the Tornado back to drogue chutes in the Typhoon seems to me to be a bit of a retrograde step. Why isn't reverse thrust more widespread in combat aircraft?

Don't forget the Harrier! The King of reverse thrust.

Fully controlable too.

Have fun,

Yep, you're pretty much spot on. Reverse thrust uses a bunch of gas, complex systems, and additional money to not really do much of anything but make a bunch of noise. It is extremely ineffective at slowing an aircraft compared to drag chutes or brakes. The biggest "advantage" of reverse thrust is that it cancels out the idle forward thrust working against you. On my aircraft (CRJ), we get a substantial portion of our reverse thrust effectiveness by just unlocking the reversers and not even bringing the engines out of idle.

I'm confused about the reverser on the Viggen... are there interior doors that deflect the jet blast??

Canceling out idle thrust isnt an issue on most fighters, as they have an engine nozzle that is open at ground idle to prevent any thrust from being produced. This nozzle probably also makes it a bit difficult to integrate reversers, but the Tornado proves it can be done. Id imagine the benefits of reduced brake wear just dont stack up enough for the military to consider it. On a slightly related note, do any of the heavier aircraft, like the B-52 or B-1, have them?

You can see them halfway deplyed here. The thrust is steared out the slits on the side.

Well that clears it right up! Thanks!
