The following design tools have been developed by the SSDL members for use in conceptual space vehicle design process. For additional information or questions regarding the availability of these tools, subject to the disclaimer below, please contact the graduate student listed. In many cases, this contact information may be obtained on the SSDL Alumni page. We ask that you acknowledge SSDL and the use of the tools in any publication or subsequent research project.

Planetary Entry Systems Synthesis Tool (PESST) : The PESST framework has the capability to estimate the performance and mass of an entry system using user-defined geometry, hypersonic aerodynamics, flight mechanics, thermal response, and mass estimation. Earth and Mars atmospheres are preloaded with the ability to also use either user-defined or GRAM atmospheric models. Trade studies can be performed by parameter sweeps to gain an excellent understanding of the design space for conceptual studies. This framework is broadly applicable to conceptual studies of EDL systems with varying landed precision requirements. (Otero)

SCORES: Web-based Liquid Rocket Engine Analysis Tool (Way)

SCCREAM: Web-bases RBCC Engine Analysis Tool (Bradford)

T-BEAT:  Web-based Turbine-Based Engine Analysis Tool (Bechtel)

PHATCAT: Powerhead and Thrust Chamber Analysis Tool for Liquid Rocket Engine Cycle Analysis (Cormier)

T-CAT: Thermal Calculation Analysis Tool for TPS Sizing on Advanced RLV's (Izon/Cowart)

Interplanetary Mission Calculator: Interpolate from a database of planetary missions delta-V's with or without swing-by. (Sakai)

Orbital Trajectory Animator: The Trajectory Animator is a Java-based program designed to simulate the orbit of a spacecraft using a programmed thrust based on the spacecraft's position in the orbit. This program is capable of handling both low and high thrust simulations.
