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

Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

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…

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... : roll:

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

The only thing safe in the future. It is that there may chance that it conforms to our expectations ...

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...
