HYBRID ROCKET ENGINE TEST FACILITY DESIGN
Havacılık ve Uzay Teknolojileri Dergisi, 2016 Hybrid rocket engines is relatively less researched subject of chemical rockets. Using fuel and oxidizer in different phases hybrids are safe and cheap. Yet, they are not generating enogh thrust to deliver heavy payloads to edge of space.
