Sadly not.
The fuel of mass 'dm' must have been accelerate
Good news...
The results came back from the state DTSC lab last Friday. The results
were that they found NO DETECTABLE levels in any of the recent samples
from our property.

Okay, in an "ideal" drag=free system, thrust increases with centrifugal force
as chamber pressure, etc., increase.
The specific kinetic energy of the propellant in the inertial frame must
increase as it flows to the tip engines,

I may be missing part of this scenario, but there seems no reason for rotor
tip speed to equal exhaust velocity. I would think rotor tip speed would
increase un

A vehicle with the capacity to hover must have the possibility of deep and fine
throttling.
Realising that with a classic biprop prop
