Dual Mode Ramjet (DMRJ AKA Scramjet)

̽����Ƶ Dual Mode Ramjet (DMRJ, aka "Scramjet") Engine Technology offers the following features:

• Lighter Weight
• Reduced Heat Load
• Better Operability and higher Specific Thrust

A Dual Mode Ramjet is a Propulsion System which, dependent on the Flight Mach Number, operates in two Modes.

• Mode 1: As a Ramjet With High Mach but Sub-sonic Combustion; the “Throat” is provided through Thermal Choking. An “Isolater” is required for lower Mach operation to provide a Combustor Entrance Pressure higher than the Combustion Pressure.
• Mode 2: As a Scramjet With Supersonic Combustion.

Primary challenges are Fuel Conditioning, Vaporization, Mixing, and Combustion and Thermal Management.

DMRJs are suitable for Long Range Missiles and Reusable HCVs.
