Dragonfly ~
Rotor - Blade - 8-H-12 - AluminumOverview:
All of the following pages are SynchroLite pages, but the only difference between the Dragonfly and the SynchroLite blade is the length.
Outside Web Page:
Vortech extruded aluminum blades.
The price from Vortech is $650.00 US for a pair of 9-foot long blades. Three pair are subject to a discount of 10%. Should phone Eagles Perch for a second price.
The spar is not included but the root cap, tip cap and mounting plates are. The reverse rotation may necessitate producing opposites of all of these.
Weights: (from
MODULE: Rotor)If (Chord = 0.3958) ['Chord is 4.75"] then Multiplier = 0.34375
The values below are for an 8" chord. They are then adjusted by the Multiplyer
RotorHub = 2 * Multiplier 'Item 0306 'Weight is 1/2 of rotor hub weight of 3.
RootCap = 0.0221 * Multiplier 'Item 0299
BladeGrip = 0.5556 * Multiplier 'Item 0297 'Considered 12" long.
'TipWeight comes from box on form 'Item 0323
TipCap = 0.0309 * Multiplier 'Item 0298
Blade = 1.4112 * Multiplier 'Item 0351 'Pounds per foot.
NoseWeight = 0.80766 * Multiplier 'Item 0330 'Pounds per foot.
It looks like Access is all setup to run the 8-H-12 blades calculations, such as coning angle etc etc.
