Notes:
It appears that the V angle can be changed from 22-degrees to18-degrees (maintain 25" stagger) with the same blade-hub clearance if the inward lateral cyclic is restricted by an additional 2-degrees. This will have the advantages of 1) reducing the torque pitch coupling, 2) having higher blade tips at the side and 3) reducing the yaw rate so that it is closer to the longitudinal rate.
Tere are two potential engine configurations, the 4-cylinder opposed and the 3-cylinder inline. The 4-cylinder opposed must be mounted with the crankshaft longitudinally. The 3-cylinder inline can be mounted longitudinally or laterally, but the gearbox will be different for each
Hover Statistics
Momentum Method
Power to hover = 39 HP. = 16.6 lbs / HP
Blade Element Method
Theta is 7.0 degrees for lift of 650 lbs. in hover.
Power to hover = 43 HP. = 15 lbs / HP
Hollmann Program "Synchro Hperf.BAS"
Theta is xx degrees for lift of 650 lbs. in hover.
Power to hover = xx HP.
Forward Flight
Hollmann Program "Synchro Hperf.BAS"
Theta is xx degrees for forward speed of xx knots
Power required = xx HP.+/-
Final Assembly:
These will be the sub-assemblies, for transportation;
Cables etc. in tail boom will be part of Control - Flight, but it must be build out in the in the tail boom's final assembly.
Can they be billed to both Control - Flight / Tail
I.e. 2 routes to final assembly?
