Development of Universal Flight Trajectory Calculation Method for Unguided Projectiles
Flight trajectory Unguided projectiles Trajectory radar measurements
2009/10/10
A universal external ballistic trajectory model for unguided projectiles is developed in this study. The mathematical model is based on the Maclaurin Series. The Maclaurin Series coecients are predic...
A New Control Method for SSPS Orbital Transfer
Space Solar Power Systems Optimal Orbital Transfer Solae Electric Propulsion
2009/8/19
A new control method for the orbital transfer of the Space Solar Power Systems (SSPS) by the solar electric propulsion is presented. In this method, SSPS is launched from a place near the equator such...
2-D and 3-D inversions for frequency-domain helicopter-borne electromagnetic method
helicopter-borne EM 3-D inversion finite difference modeling double dipole
2009/3/5
The frequency-domain helicopter-borne electromagnetic (HEM) method is the most suited for resistivity mapping in very large areas. Another advantage of HEM survey is to provide information that allows...
