I'm a bit of a skeptic but that does look cool, looks even more wrong than a when you see a Harrier hovering!

Those look so wrong with all the doors & bendy tailpipe.

Not to mention it using a massive amount of elevator deflection at those low speeds (and in the "wrong" direction too............) ;-)

I actually am starting to like the looks of the aircraft.

Still not convinced by the performance figures...but hey ho

Also........



....is this not the smallest flight deck handler in the world??? wink

That's a great video, and really interesting to watch. There are so many flaps and doors that open up when ready for take off.

The deisgn of the engine intake is interesting on take-off, doesn't it amount to a giant airbrake on top of the aircraft??

Thats the door/air redirect for the lifting fan.

The pair of doors behind the lift fan inlet are the auxiliary air inlet doors for the engine

I read it helps protect from FOD as well

So much parasitic weight, such an inelegant piece of engineering; more flaps than a Women's Rugby Team.

Makes the Harrier look so much more elegant.

I really don't like this aircraft. It looks like it perdates the Harrier with that massive moving rear nozzle and the great big barn door wide open on take off. Just doesn't look right at all.

Sadly we may never get truly beautiful military aircraft again, the 'stealth' focus dictates certain angles and areas which have a massive effect on the design aesthetics, a fairly ugly compromise between reduced radar profile and aerodynamics. All the little doors and features are another compromise for a low radar profile while in flight, frankly it can be as ugly as it wants as long as it works.

I think he was referring to the engineering of the harrier

Not this collection of fans, clutches, gearboxes, driveshafts, doors and hydraulics instead of 4 spinny nozzles

Bit of both, really. I'm no aeroplane geek, but the Harrier is by far my most favourite aircraft to look at. When it is doing it's thing it just looks stunning, and doesn't look like it is going mental to do so. Up it goes, with the minimal of fuss, and taking a few Mirages to task whilst doing so. Some folks like the Spit as the most beautiful. Not me. Me likely the Harrier.

What is obvious when compared to the Harrier is how far computer controlled flight dynamics have come on in the preceding 30 years! That F35 just does all the hard work for the Pilot (including things like the elevators moving the wrong way at low speed etc). Early Harriers by most reports were a bit of a handfull for even highly experience pilots!

At least the Harrier never looked like it was straining to have a poo when it was hovering hehe

I wonder how long before they realise a short ramp at the end of the ship will help things considerably.

Americans have always been very reluctant with the ramp idea even though it gave the harrier a nice take off weight boost.

The later 12.5 deg ramp is supposed* to have given the harrier an extra ~900kg of max load, a sizeable increase for a small carrier jet. Not to mention less runway being used and more usable in poor weather / high seas.

Also as an interesting aside reading about carrier operations recently and have seen several mentions of the fact (or notion) that conventionally launch carrier planes return to land with ~25% full tanks just in case of missing the wire or being forced to hold in pattern for much longer while the harriers in marine and navy service often returned with tanks down to 5/10% due to the higher rates of landing and much shorter times holding. If that holds true for the F35 as well the real world range difference between the B and C is suddenly much smaller then the base stats imply.

With a ski jump increasing launch weight capacity (how much, I have no idea, the harrier saw good gains but was a different beast) and SRVL seeming to show promising results in more efficient landings I wouldn't be surprised if the B model only ends up being slightly down on the C's range. Iam starting to think that going for the B might not be such of a big issue as first thought. A brief guess of the numbers would see the 25% range difference between the two drop to ~10%, if the same rates apply of course.

Also interesting on some of the American boards how utterly appalled some posters are about the idea of a ramp on a ship, full tirades and abuse regarding such a 'stupid' idea and disbelief that the RN employed such a measure, the sheer hate from some regarding a long term and well proven idea seems baffling.
