MONOPROPELLANT INJECTOR FOR SMALL-SIZED THRUSTER

摘要

PURPOSE: A monopropellant injector for a small thruster is provided to supply a monopropellant over a wide range by forming a plurality of discharge ports. CONSTITUTION: A monopropellant injector for a small thruster comprises an injection plate and a plurality of discharge ports(130). The injection plate is mounted to the end of a combustion chamber. The discharge ports inject a monopropellant to the combustion chamber. The discharge ports are formed in the injection plate. A virtual line from one discharge port crosses over another virtual line from the other discharge port. The monopropellant from the discharge ports is atomized by colliding each other in the combustion chamber.
