Total Hypergolic Propellant Leak Detector System

Razor Technologies proposes to develop and demonstrate a total hypergolic propellant (both fuel & oxidizer) leak detection system. During normal storage conditions, the system will monitor and record missile canister environmental parameters such as fuel (mono-methyl hydrazine and/or hydrazine compounds) concentration in the missile canister, oxidizer (mixed oxides of nitrogen) concentration in the missile canister, temperature, humidity, pressure, etc. on an hourly basis. The propellant leak detection system will utilize a proprietary, ultra-low power motion detection circuit to determine when the missile is undergoing transport. Upon detection of transport, the propellant leak detection system will continuously monitor and record propellant concentrations and other transportation events (such as shocks) exceeding preset limits. The system will send out an alarm when a specified rate of change in concentration of propellant is exceeded (indicative of a large leak) or when a preset high value of propellant concentration is exceeded (indicative of a slow leak acting over a long period of time). Long life, conducting polymer sensors for the measurement of fuel and oxidizer concentrations will be used. This project leverages on previously successful SBIRs that have led to the development of a commercially available MMH sensor and missile canister environmental monitoring system.
