Purpose – To develop and find the effect of combination of four cycle design variables that minimizes the specific fuel consumption (sfc) of a turbofan engine. Design/methodology/approach – After choosing the four variables, namely bypass ratio ( B ), fan pressure ratio, overall pressure ratio,...
Purpose – Hill equations have definite limitation in the design of multiple spacecraft formation flying in eccentric orbits. To solve the problem, the design method of spacecraft formation flying in a circular reference orbit based on Hill equation can be generalized and applied to spacecraft...
Purpose – To improve the accuracy of mapping of space‐borne three‐line array cameras. Design/methodology/approach – Derivation of the mathematical model and the error model of the three‐line aerial triangulation, the creation of the simulation data, and the analysis and comparison of the...
Purpose – An architecture is proposed based on the torque mode operation for the combined energy and attitude control system (CEACS). The CEACS energy storage and attitude control performances are demonstrated. Design/methodology/approach – All the relevant system equations are established. The...
Purpose – To suggest a new revolutionary electrostatic linear engine. Design/methodology/approach – Methods of the electrostatic physic are used for research. Findings – Theory of this engine is developed and its possibilities researched. Research limitations/implications – This engine gives a...
Purpose – To study the effect of rocket mass and an intermediate mass on the critical flutter load of a free‐free beam (missile‐like structure). Design/methodology/approach – A finite element model of beam considering shear deformation and rotary inertia, based on Hamilton's principle applied to...
Purpose – To optimize the shape of a cascade where velocity (or pressure) distribution is optimally given. Design/methodology/approach – The semi‐inverse method suggested by Ji‐Huan He is applied to establishment of a variational theory for the discussed inverse problem. The boundary conditions...
