Re: That game of darts...

Hi crazydoc,

Yes, You change the rotor disc AOA to your forward motion as well as shifting the weight by introducing an outside force to another force via your controle stick. You can not change the pitch of the blades like in a helicopter.

Re: That game of darts...

So let me be the thorn in the bush again, but i cannot agree that gyroscopic pres is the reason. The AOI or AOA DEF does but GSP has very little to do with it. You still need an outside force to make another force move........

Re: That game of darts...

Gyroscopic precession has *virtually* nothing to do with a helicopter's rotor. Gyroscopic precession is little more than a simplistic means of describing the basic end result at the rotor, after the application of a cyclic input. (i.e. 90-degrees later ~ basically ). It is no good for explaining the...

Re: That game of darts...

Ebie, I think what PtKay is (correctly) pointing out is the mistaken assumption that the gyro disc attitude is changed by means of weight shift (i.e "pulling or pushing up, down,left or right etc.as per a trike wing - albeit on a gyro via the control linkages). This is not the case. It is gyroscopi...

Re: runway for gyro

Hi Pepper, It all depends on the pilot........how much exp. he has on type. If the pilot is a newbie, one would like to take away as much distacting factors on take off and landing as possible. For example like short slopiing , crosswind runway............. In my humble opinion it also depends on th...

Re: Gyroplane Stability and Aerodynamics - Glasgow Universit

Hi dave, yes the vpm needs one according to the report , but the report does not say that all gyros do,like it is claimed.....


Anyway did not want to start a debate again. Ony posted info i was told to go and check out. People will anyway believe what they want to believe.....

Re: Gyroplane Stability and Aerodynamics - Glasgow Universit

What is your email.

Tbird , you need to remember that the testing was done on 5 differant aircraft as well as the vpm/magni. And this was foun to be the same on all of them.

Anyway just some info i found on testing done by Glasgow. Who apparently is the best in doing the testing.......

Hi t bird

This is not about the RAF. This is what is said in the repot by the profs.

If you wanna fit a tail to your RAF you are more than welcome to do so....

Re: Gyroplane Stability and Aerodynamics - Glasgow Universit

It is worth noting that the modification proposed to solve the stability problems which led to the grounding of the Air Command gyroplane type comprised principally, in aerodynamic terms, of the addition of a pod and a tailplane. These tests suggest that this modification would not be very effective...
