Special Issue Information

Dear Colleagues,

The demand for space applications is growing, and the need for space transportation is gradually expanding in both military and commercial spaceflight, with rapid and low-cost spaceflight activities being the current trend. In order to enter space, it is indispensable to have powerful propulsion devices, including liquid rocket engines, ram engines, and their combined engines. Rocket engines are jet engines that carry their own propellant from the vehicle and do not utilize outside air, while an aero-engine is a device that utilizes oxygen in the air for combustion with fuel. Carrying out the dynamic performance analysis and control of engines for aerospace is conducive to promoting the development of engine theory and technology.

This is a call for papers for a Special Issue entitled “Dynamic Performance Analysis and Control of Engines for Aerospace”. This Special Issue will provide a venue for scholars and researchers to share their most recent theoretical and technical successes, as well as to highlight key topics and difficulties for future study in the field. The submitted papers are expected to raise original ideas and potential contributions to theory and practice. The research topics include, but are not limited to, the following:

  • System characteristics;
  • Spray and flow;
  • Combustion dynamics;
  • Rotor dynamics;
  • Reliability and life analysis;
  • Heat transfer and thermal protection;
  • Propellant characterization.

For the guide vane adjusting mechanism, precision represents the primary design requirement. Meanwhile, due to the presence of aerodynamic loads under actual operating conditions, stagnation forces emerge that affect the mechanism motion characteristics, including the response speed and precision. This paper establishes kinematic and static analysis models of the guide vane adjusting mechanism through analytical modeling methods, investigates analytical approaches for mechanism adjustment precision and stagnation force, and conducts error and sensitivity analyses of the mechanism parameters based on these analytical models. Building upon this foundation, an optimization design method integrating adjustment precision and force transmission performance is proposed using a multi-objective genetic algorithm. Optimizing the critical design parameters, such as the mechanism dimensions and positions, can enhance both the adjustment precision and force transmission performance. Through case studies, significant reductions in motion precision errors and the peak stagnation force and maximum differences in stagnation force were achieved, validating the feasibility of this optimization design approach.
