NOW ! .
Everyone knows if you hold a spinning bicycle wheel by the axle , and lift it it goes sideways , & V c V .
So we need to hold TWO bicycle wheels and see if the do the same thing spinning opposite directions .
Or we could get two bicycle wheels on ONE AXLE , get Brett to hold it . And spin them in opposite rotations .
To see what happens . When he lifts or moves it L & R or drops it .
Gyro & P would by canceled or substantially negated .
I think the only way to observe the airflow is with visable air , & whilst airborne by camera on airframe. Aimed at props .
Id thats whats being investigated .
Clunk tanks , and flap movement through manouvres would be of intest also .
==========================================================================
" How does this apply to CLPA ship? Doubtful it means much "
On nasty little British Aircraft Carriers , it meant a great deal . Like with a Jet .
When the more powerfull Griffon Spitfire was introduced , The throttle had to be progressively opened . . .
as the swing W F O on the ground was uncontrolable .
However . You dont get ' swing ' with the Contra Props .
NOW , WIND .
Is comparable to Acceleration & deceleration .
Where the Torque Reaction is prominant .
WIND - Varying Airspeed . Even if its just steady wind . It'd be Headwind & tailwind .
Thus the BALANCE of the forces on the airframe at the start & exit of manouvres ,
As well as those through them ,
Would be significant .
Most will have noticed a reluctance for the nose to raise from level , down wind . If it blowing past 18 Kts .
Also the entry to Clover & the turn into the top leg of the hourglass can be problematic . In severe wind .
Be intresred in Matt P's observations there .
Been looking for a ' everything down ' Picture of a Seafire 47 on approach . Contra Props .
A Go Around with a conventional prop , from ' on the verg ' is problematic in the extremme .
Whereas with the contra props it is almost routine .
IN WIND , particularly choppy air , for AEROBATICS , the contra props likely are a significant advantage .
================================================================
A aside , was that the forward area increase ( from dual propellors ) needed compensateing tail area for directional stabilty ,
the rear area being a bit marginal on the Supermarines , bar the very last series .
