PCE-Based Robust Trajectory Optimization of Launch Vehicles via Adaptive Sample and Truncation
Publisher: ASCE
Abstract: To reduce the sensitivity of trajectory to uncertainty, this paper concerns the robust trajectory optimization of the solid ascent launch vehicles with the uncertainty of aerodynamic parameters and engine mass flow. Due ...
Temperature Field Measurements in Swirl Spray Flames Using Two-Line Planar Laser Induced Fluorescence Thermometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the temperature fields in a centrally staged swirl spray combustor using two-line OH planar laser induced fluorescence (PLIF) thermometry at elevated inlet pressures and temperatures up to 0.62 MPa ...
