Dear friends,
My helicopter with a teetering rotor and two composite blades is not stable enough and has very bad autorotation characteristics.
To improve these properties I decided to add mass to the blades by injecting epoxy to the tips. Total addition of the weight was 28%, but in the terms...
Dear Engineers,
I'd like to perform an estimation of the gear transmission eigenfrequency. Does somebody know about some useful algorithm for such analysis or a standalone program?
Thank you.

Hi,
In the calculation of forces (in the MitCalc) in helical bevel gear pair [20/46 teeth pinion/gear, 20° pressure angle, 30° helical angle, Module 2, transferred power 15 kW, pinion speed 6200 RPM] I get a negative axial force for the pinion. This means that the force is pulling the pinion...
I have encountered a strange problem when our small rotorcraft (2 meters rotor diameter, rotates clockwise when looking from the top) is hovering while an oncoming wind (about 10 knots) is blowing onto the platform. The craft begins to roll counterclockwise (if looking at the craft from the tail...
