... Design optimization Helicopter performance Rotor blade design The design optimization process is outlined in Figure 1 . This process is initiated with a given helicopter configuration and specified flight parameters, and then the optimization process for rotor blade is conducted as the next...

... or by lowering the launch vehicle mass (mainly by the engine mass). Consequently, to achieve the desired final velocity, the launch vehicle initial mass (M_{0) should be reduced, which can be achieved by increasing Īsp and decreasing engine mass. Thus, the design optimization}...

...Tobias Bach; Tanja Führer; Christian Willberg; Sascha Dähne Purpose The purpose of this paper is to present a structural design and optimization module for aircraft structures that can be used stand-alone or in a high-fidelity multidisciplinary design optimization (MDO) process. The module...
