Deliverable D1.2, part I: Report on Analytical Adaptive Rotor Studies

Full text not available from this repository.


This report is about computation of the rotor performance based on the baseline rotor definition from deliverable D1.1. Rotor blade adaptive twist, chord extension and combination of both are investigated with respect to hover figure of merit and rotor thrust enhancements, relative to the baseline rotor. The report is divided into two parts. The first part makes use of textbook-like Blade element momentum theory with certain refinements explained in detail. Results are computed assuming rigid rotor blades using Excel. The second part is a repeat of these computations using DLRs S4 isolated rotor code, which employs elastic rotor blades, nonlinear aerodynamics including stall, compressibility and various rotor wake modelling tools. Especially that report will include the modified aerodynamics of the morphed airfoils that are not considered in the first part.
