I've looked around for info about the Lerche and can't find much other than it never got beyond the drawing board in 1945. I understand that experiments were carried out using the same concept in the 1950's but i dont understand the aerodynamics of it.
How does it generate lift after it makes the transition to level flight?
With the way it generates lift- would it effect whether it was inverted (discounting the effects on the pilot)?
Could piston engines generate a sufficient power-to-weight ratio to allow for VTOL?<div class="ev_tpc_signature">

http://forums.ubi.com/images/smilies/10.gif I have it on good authority that it could never have flown, and the Big O tinkered with the flight model.<div class="ev_tpc_signature">

Why choose the Lerche to model? Why not just make a German UFO...an Uber Flying Object? Maybe something like the little green-$hi+ firing space fighters from Independence Day.

The lerche would have flown using its duct as a circular wing.

Piston engines certainly have sufficient power for VTOL flight; there are plenty of piston engined helicopters out there.

The Lerche almost certainly wouldn't have worked exactly as first drawn, but then most aeroplanes change somewhat between drawing board and production hardware.

VTOL is technically challenging, so the chances are that the Lerche would have gone through greater changes than a more conventional aeroplane.

With that said, I'm quite convinced that it could have been made to work; Convair's Pogo was conceptually similar. It flew, and it managed to make transitions.

But, as with the Pogo, I expect that its practicality as an operational fighter might have left something to be desired due to a combination of nasty failure modes and "difficult" landing characteristics.

Oh, and the fact that it would almost certainly fall over if left outside on a windy day!

All I know is I can't land the thing properly to save my life.

I ended up taking advantage of its disturbing manueverability at low speeds and basically just coming to a stop on a dirt road, horizontally.

Granted, I broke the outer frame, misaligned the propeller blades and rendered the engine inoperational, but nothing a quick tow to the hangar couldn't fix!

They already have it! Its called the 109 G2.<div class="ev_tpc_signature">

The lerche uses an unobtainium reality nullifier field to fly. The german scientists came up with it in 1945, it's why the won the war, don't you know.

The Lerche certainly raises questions. My two cents :
First, as someone already said, piston engined helicopters do exist, and work. So much for "never would have the power to take-off".
Second, about stability : the Germans could build rockets that actually took off vertically... yes, and they didn't fall over http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif . The Lerche could basically have used this kind of active stabilisation.

No need for raaaaaaaaid or Lerche just hope in your La7 and enjoy your UFO ride, or, if bored you can swith to TB3 adn go for some nice endless looping for a change...
Why pls screem "UFO!" when they see unusual shapes nad forget isntantly about all those "Imposible Flying Objects" we already have in the game.
Lerche is bigger beast then let's say I185M71..<div class="ev_tpc_signature">

I'm dislectic, so please bear with me...

OK, can someone explain how tEh Lerche turns? (literally, the physics involved not it's performance)

or how it performs when damaged?<div class="ev_tpc_signature">

Where is raaaid when you need him ? He could solve this.

It would work like the one in this video. Provided it was made out of foam.http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif
Scroll to the bottom for the proofs. Be sure!

A speck of dirt on your windscreen could turn into an enemy fighter in the time it took to look round and back again. A little smear on your goggles might hide the plane that was coming in to kill you.

Well, the proofs in the pudding. And that thing can maneuver something wicked.

What do the naysayers have to say about that? http://forums.ubi.com/images/smilies/winky.gif<div class="ev_tpc_signature">

Perhaps they could have made it out of some light weight composites? Still would have been a death trap though. I wouldnt voulunteer for test pilot on that thing.
