Experimental Sounding Rocket Association

The Experimental Sounding Rocket Association (ESRA) is a small-scale student rocketry club underneath the CSULB branch of AIAA (American Institute of Aeronautics and Astronautics) that focuses on experimental concepts and intensive engineering projects. Our club intends to enter competitive competitions such as Spaceport America in the near future.

ESRA aim's to provide more opportunities for women on campus through club events. Our current membership base is 50% female.
 

2023-2024 Year in Review

After a successful re-start of ESRA in the Spring of 2023, designing, building, and launching a solid rocket in less than four months, ESRA set its eyes on developing a liquid system next! Instead of taking a build, fail fast approach and spending tons of money, ESRA took a calculated, iterative design approach to building their future liquid propellant systems. Under the mentorship of CSULB's Dr. Schmitz and former engineers from Aerojet Rocketdyne, ESRA utilize methods of multidisciplinary optimization to build an open-source vehicle sizer code base to output various liquid system configurations. Code outputs include, fluids piping length, regulator Cv, engine geometry, apogee/thrust achieved, Isp, OF ratio, etc.
