How to properly design a VTOL/ADAV helicopter-plane?

[Christophe]

All versions of the f35 are vtol?

Seems not to me...

[Remundo]

no, it's a variation.

There is the conventional plane
A short takeoff version
and a last VTOL/ADAV

This is the one that crashed. A mrd happened on the rebound, the rear of the plane suddenly rises (aero effect? ​​Control error?) and causes the nose to pitch down, the front landing gear does not support the lever arm and it goes away in peanut.

Yes, I saw that…for the pilot to decide to eject on the ground, he had to mess things up…

[Remundo]

the pilot may have been afraid of the fire. There are white fumes which I can hardly understand the cause.

all this in a toy filled with $150 million kero...

Here are the blowers of the bouzin... you have to synchronize all that. There are obviously ground effects when approaching the cow's floor.

based on a support quadrilateral.

Apparently there is only one blower and the flow is distributed in 4 "nozzles" which are not identical.

it must be funny...

A newcomer in the VTOL: AIR ONE (Breton?)...it's progressing, it has a carrier wing but its engineers still haven't understood that a VTOL with 4 nacelles was absolutely fatal...in the event of failure ( the carrier wing should help however if the Vxy is sufficient...).

I would never set foot in a 4-nacelle VTOL...

I found this very progressive and illustrated video that demonstrates drone control/stabilization.

A named ADAV "Autoflight's Property I"

whose design for me goes in the right direction, with a mixture of multirotors (6, therefore very redundant) ascending supported by 2 propellers of horizontal propulsion.

The first tests are encouraging.

From my point of view, the airplane/helicopter transitions must use 2 independent systems, one to carry, the other to propel.

There's Zapata who has just designed a new one but it's hybrid... Electric and thermal

[Christophe]

It's good he is progressing: he understood that the turbines were big shit at zero V0!!

Too bad we had to waste X millions...to clown once in front of jester 1st on July 1th!

Well, he's richer than us...
