HELICOPTER HUB LOADS

[jagannath]

With reference to the main rotor hub loads in rotating system and vibratory hub loads in non-rotating system. There seems to be no first cut closed form formulas or empirical in nature but rather elaborate CAMRAD/aeroelastic analysis which requires substantial cost and time. I want to know whether any text book/literature which can give approx/first cut from fundamentals about the nature of hub loads. I have seen quite a few books like harris/Johnson which give some insight into hub loads.

Good Luck!
I senses that you're way past the technical level of most folks (including me) on this forum.

Hub Loads

Unless you already work there, I should think the people at Hindustan Aviation in your town could help. As Shawn implied, it is anything but a simple subject. If one looks at the various OEM's and the methods of blade attachment, inherent rotor basic design choices, different rotor control system attachment methods and the like, it is anything but a " cookbook " situation.
