ABSTRACT:
A fuel feed method and apparatus for a turboramjet engine having a combustion chamber operable as a turbine engine afterburner and as ramjet engine combustion chamber is disclosed which features the concurrent injection of kerosene and hydrogen. At low Mach numbers, kerosene is the predominant fuel injected, while at growing speeds, hydrogen is injected in increasing proportions. This provides for a short combustion chamber length while minimizing the on-board fuel load and benefits especially small-size hypersonic aircraft.
