STS_SolidSnake 0 Posted May 6, 2002 Ok if the Harrier takes off verticaly, then in the air it goes to jet mode shouldnt it fall to ground when does little engines turn up ? Share this post Link to post Share on other sites
LordZach 0 Posted May 6, 2002 i think it has thrust seperate from the jet engines, so you simply engage the jet engines when you are at the desired height. Powerplant: one Rolls-Royce Pegasus Mk 106 vectored-thrust turbofan Thrust: 21,500 lb (95.64 kN) Share this post Link to post Share on other sites
KTottE 0 Posted May 6, 2002 The Harrier doesn't fly straight up, it's tilted forward. So that when the small VTOL engines are tilted backwards, it starts to fly forward, as opposed to falling straight to the ground. Share this post Link to post Share on other sites
Intruder 0 Posted May 6, 2002 The nozzels a rotated gradually enough to pick up some forward speed at first. As the speed increases the wings will start to generate lift and the nozzels can then be rotated towards the back even more. At a fast enough speed, the nozzels are rotated to the horizontal position, and the wings provide all the lift. Share this post Link to post Share on other sites

peeps 0 Posted May 6, 2002 i have pretty limited knowledge on this and its early in the morning for me (yes i no its 11.30am) but im sure harriers don't actually work like that, they use the upthrust to keep them in the air until they have enough speed to turn it off and then fly like a normal plane Share this post Link to post Share on other sites

Paratrooper 0 Posted May 6, 2002 This is correct, they do not have two engines one of which is 'turned off' at the desired level... Share this post Link to post Share on other sites

Intruder 0 Posted May 6, 2002 I believe the Yak-38 had two engines, one for vertical flight and one for horizontal flight. Wasn't as famous as the harrier though. Share this post Link to post Share on other sites

Intruder 0 Posted May 6, 2002 Trust me, I done a paper on VTOL aircraft in my final year of university  Links and info here: http://www.fas.org/man/dod-101/sys/ac/av-8.htm Share this post Link to post Share on other sites
KTottE 0 Posted May 6, 2002 Intruder has done a paper on this subject, and the rest of us supporting his theory has common sense. So I would believe us =) Share this post Link to post Share on other sites

Intruder 0 Posted May 6, 2002 Didn't put the Triebflügel in it. I did inlude various coumpound helicopters, V-22, and the JSF, amoung other aircraft. It was set out in three sections, past, present and future. Got 29/30 for the paper and a presentation Share this post Link to post Share on other sites
