Did the F-111 deploy a chute?

Does this mean that Typhoon pilots are trained in packing parachutes in case they're forced to land somewhere there's no trained ground crew?

No, the size of the wing and wing sweep was designed for carrier landing speeds and short landings, even if the USN never eventually bought it.

Tupolev 104 and 124 both had brake chutes as well as the Caravelle. As for deploying before touchdown; Mig 29s seem to do this as normal. (NB BEA Tridents were cleared to engage reverse thrust before touchdown but that's another story)

See here for an amusing Lightning chute story by Roland Beamont.

I think I've read that XH558 will not require the chute to stop at it's new reduced weights, but that it will still be carried for emergency use. Should make airshow trips a bit easier!

And don't chutes come in handy for de-spinning, or is that just a last resort option?

The TSR2 used a 24ft diameter brake chute too.

TSR2 Chute

The TSR2 had a reefed chute. Efficiency of the chute as a slowing device is obviously related to V squared. If you pop a big one out at high landing speeds, it would need to be of v strong stuff. So TSR2 designers had a big chute which was "reefed" on initial op and at some lower-than touchdown-speed, was unreefed and allowed to develop its full area. (Not sure how the auto-reefing bit worked)

It was also used to get the Victor out of a super stall.
High T-tail blocked by the main plane in a stall. No control response from the elevators unable to recover. Popping the chute would drop the nose allowing undisturbed air over the tail and the controls would respond again.
Sadly a couple of crews were lost before this was discovered.

The Jaguar 'chute, when deployed, presented the most obvious degree of 'performance' available from the whole aircraft .

Cutes as air brakes

TU104's normal ops. LHR & LGW airport staff retrieved chutes, flying spanner stowed new chute & took used one home to get repacked. Some times, if I had time, would help the spanner onload new chute, 'twas fun for a lad.

The drag chute is used on a number of business jets, among them Dassault Falcons, Learjets and Cessna Citations.

There was an Aussie F-111 belly landing a while back (check footage on youtube). No drag chute but there was an arrestor hook.

Much fun being dragged across SMG airfield by a Victor chute.

God bless the Local Controller who insisted it was the same size as FJ one, and me being daft enough to believe him

The F-117A Nighthawk uses a chute because it doesn't have any flaps.

From US Air Force Technology.....

" The elevons do not act as flaps to reduce the rate of descent for touchdown, so the landing speed of the F-117A is high, at about 180mph to 190mph, and a drag parachute is used."

I always wondered what flaps did. I thought the pilot controlled the rate of descent.

In the second world war pilots of damaged B17s used to get the waist gunners to stream their personal chutes out through the gun ports (with them anchored to the aircraft not themselves) to help slow them down incase the brakes weren't working properly. Bit heath robinson but it helped apparently.

Flaps don't reduce the rate of descent, they actually reduce the stall speed of the wing, which means that the landing and approach speed are reduced. However, as a secondary effect, for a given glideslope angle, the rate of descent will be reduced if the forward airspeed is reduced.

Hawk 128 has a brake chute, I believe this is the latest military aircraft to be fitted with one (although not yet RTS)!
