Earth Reentry Tool for Preliminary Mission Analysis
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 2
Abstract
The preparation of atmospheric Earth reentry vehicles requires the estimation of heat and mechanical loads along the trajectory, as well as the impact point. A dedicated tool for axial symmetric capsules is prepared for trajectory propagation, providing relevant data for the thermal protection system sizing, such as the heat flux in the stagnation point calculated with five different models. Translational dynamics only are considered for the moment. The aerodynamic drag is computed using the minimal input as Mach dependant curves. The Reynolds number influence is also included, since the flow regimes to compute the drag coefficient are derived from a preliminary reference trajectory. Automatic generation of quality plot files is included, as well as 3D plot objects for Matlab, for later usage.

Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage. Part 6: A Panel Method for Non-Lifting Bodies Oscillating in Subsonic Flow
In the sixth part of this series, we continue our study started in the previous article, i.e., we present the basis of the method for calculating the unsteady airforces on oscillating non-lifting bodies. The method propo...
Calculation of the zeros of some special functions
We consider solutions, with infinity of zeros, of real second-order linear differential equations. The graph of a solution locates the zeros with a certain precision, which means that zeros are between some successive nu...
