Kaman Seasprite rotor questions
Can anyone with experience with the Kaman Seasprite answer the following questions?
1. Did the servoflap rotor control make any difference in how the helicopter handled versus conventional rotor blade feathering?
2. Can you list the pro's and con's of servoflap rotor control?
3. Is a servoflap system easier to maintain? It seems there would be less highly stressed components.
4. Since Kaman's patents have long expired why don't other manufacturers use servoflaps?
I would be very interested in any comments others may have on the benefits or liabilities of servoflap rotor control. If you would prefer to discuss this offline please email me.
Thanks,
Rene
