An Aerospike nozzle is used over a Conventional Bell-shaped Nozzle because of its additional advantages, such as altitude compensation. However, It faces major drawbacks, i.e., thermal and acoustics effect (excessive heating and excessive sound ), which degrade its efficiency. In order to keep that in mind, we focused on Truncation of the nozzle to optimize the nozzle and make it more Efficient. We have a compact Butane fueled Rotating Detonation Engine setup with different aerospike nozzles. First of all, we had experimentally tested each one of them. The experimental setup includes an Ignitor, Dynamic plate, Spike, Combustion Chamber, and Fuel Oxidizer Injector. Experimental tests revealed that 40% truncated nozzle gives best efficiency, and efficiency increases with increase in truncation upto 40% which is further being verified with CFD analysis of each Aerospike nozzle too. The Main aim of our research is to experimentally study the effect of truncation on aerospike nozzle.
