Abstract:  The current state-of-the-art for entry control systems is rooted in heritage entry, descent, and landing (EDL) systems such as Apollo and Mars Science Laboratory. These rigid entry vehicles used Reaction Control System (RCS) thrusters, installed within the backshell, to achieve the desired bank command profile [1]. In recent years, NASA has invested in game changing entry vehicle technologies, including the Deployable Entry Vehicles (DEV) concept. DEVs are radically different from rigid entry vehicles because DEVs have no backshell, making unavailable the typical locations for installation of RCS thrusters and associated fuel lines. In order to overcome this challenge, aerodynamic control systems are being considered as the primary means of entry precision targeting for DEVs. Dr. D’Souza will discuss NASA’s Pterodactyl Project’s lessons learned from characterizing the mechanical feasibility and targeting performance of an aerodynamic control system (flaps) installed on two variants of a mechanically deployed DEV technology called the Adaptable, Deployable, Entry and Placement Technology (ADEPT).

This seminar is optional for students enrolled in AE590. 

This seminar was moved to CIF 2039.
