A rigid two-bladed helicopter rotor mounted with no mechanical constraint of its teetering and feathering motions is analyzed with regard to the stability and controllability achievable with a simple feedback moment linearly proportional to teeter angle. Subject to confirmation by a detailed design study, it is tentatively concluded that the level of stability and control practically achievable with such a system would be adequate for tip-jet-driven very-heavy-lift helicopters. It is further concluded that the outlook for relatively low vibration levels is favorable.
