hypergolic fuels


    Most fuels, with the exception of hydrogen, are liquids at ordinary temperatures. Certain propellant combinations are hypergolic; that is, they ignite spontaneously upon contact of the fuel and oxidizer. Others require an igniter to start them burning, although they will continue to burn when injected into the flame of the combustion chamber.

    A “hypergolic” is a rocket fuel so potent that it self-ignites when combined with other hypergolic fuels. In the sports industry, biometric data has been referred to as “the new oil.” We believe that this data is a metaphorical hypergolic. When combined with other “hypergolics” in the sports technology space, they ignite, creating exponentially more power, thrust, and motion to ...
