Expendable Turbojet To Be Used On High-Mach Missiles
Rolls-Royce announced Friday it has successfully completed an
initial test of its advanced, high-specific thrust YJ102R engine at
the Indianapolis, Indiana facility. This test is the first of a
series to be performed by LibertyWorks, the company's research
unit, and is designed to validate critical performance criteria
under its High Speed Turbine Engine Demonstration (HiSTED) contract
with the US Air Force Research Laboratory (AFRL).
"Partnering with the Department of Defense to create this new
capability is an exciting opportunity for LibertyWorks," said Phil
Burkholder, Chief Operating Officer for LibertyWorks. "The unique,
power dense design of this engine has the potential to take
high-Mach propulsion to the next level. Validating the progress
achieved to date is a significant milestone and critical for the
HiSTED program."
HiSTED is a joint DARPA/Air Force initiative to design,
fabricate and ground test a high Mach expendable turbine engine.
The engine is also expected to power Lockheed Martin's
Revolutionary Approach to Time-critical Long Range Strike (RATTLRS)
vehicle. The RATTLRS program is a supersonic, science and
technology missile flight demonstrator effort sponsored by the
Office of Naval Research.
Additional engine testing is scheduled to demonstrate its
ability to achieve transonic acceleration and Mach 3+ cruise speed.
The success of these tests will lead to a first flight
demonstration of the RATTLRS vehicle.
The HiSTED engine is a high-temperature,
moderate-pressure-ratio, single-spool, dry (non-afterburning)
turbojet. It incorporates Lamilloy® technology, designed by
Rolls-Royce to enable engines to run at higher temperatures,
allowing for greater fuel economy.
