About Inaprop
Inaprop is free software for the design and analysis of Low Reynolds number free-tip propellers.
Inaprop has three design methods which are Vortex methos, Larrabee method and Adkins Liebeck method(BEM:Blade Element Momentum method). Analysis routine is not implementation yet. Inaprop function is not enough yet.And there is an excellent rotor desing and analysis software 'XROTOR', please use there.
- Design of minimum indeced loss propeller(Larrabee, Adkins & Liebeck method)
- Desing of minimum loss propeller(vortex methos)
- (Analysis and prediction of preformance curves for a given OpenProp optimized rotor design) future work
