Abstract

An improved method of operating a scramjet engine for powering an aircraft at supersonic velocity is disclosed. The method includes the steps of providing supersonic compressed airflow in a combustor, supplying fuel to the compressed airflow in the combustor, and providing a monopropellant adjacent to the airflow and the fuel. The monopropellant is effective for expanding in the combustor for mixing the airflow and the fuel for combustion of the airflow and fuel for generating combustion gases. In a preferred embodiment of the invention, the monopropellant is hydrazine and is effective for obtaining a specific volumetric increase of about 20,000:1. An apparatus for carrying out the method of the invention is also disclosed.
