It is being used under control where advanced technology is needed such as; supersonic or hypersonic planes, rockets, ceramic coating of metals, surface hardening, welding of thin film metals, plastic formation of metals. This experimental study was made to investigate; how much a reaction force by the detonation pressure can be developed in water, which has a higher density than air, whether this reaction force can be used in industry or not, and the usability of this force to propel a detonation apparatus in water. LPG and O 2 gases were used in this experimental study. A specially designed prototype detonation engine was put in a water pool and then gases sent into the engine and ignited. Detonation pressure, detonation velocity and the reaction force were measured during combustion. As a result, the Detonation Engine (DE), which was developed by us, with a 120 mm diameter nozzle and flow rate 1.2 m 3/h for LPG and 4.2 m 3/h for O 2 output that push force was approximately 5000 N. During this measurement, flowing reactant rate was 20 times more volume of DE and 0,001665 m 3 for LPG and 0.0058335 m 3 for O 2,.trinfo:eu-repo/semantics/closedAccessDetonationDetonation engineArticle2-s2.0-337496191644663Q245721
