F107 / F112 Engine
The F107 engine is the propulsion system for various cruise missile weapon systems, including the Air Launched Cruise Missile (ALCM), Sea Launched Cruise Missile (SLCM) and Ground Launched Cruise Missile (GLCM).
The F107-WR-101 is an advanced two-shaft turbofan engine which powers the USAF AGM-86B Air Launched Cruise Missile (ALCM). The engine was designed with emphasis on light weight and compact size due to the restricted internal space available aboard the ALCM. It weighs only 146 pounds and yet generates 600 pounds of thrust, which propels the 3,200 pound ALCM at a sustained speed of around 550 miles per hour. The engine burns a special high-density aviation turbine fuel which has more energy for a given volume than standard fuels. The fuel is blended to endure harsh weather conditions and long storage periods. The engine starts when the ALCM is launched from its carrier aircraft and its folded inlet fully deploys.
The F112-WR-100 is an advanced, twin-shaft, axial flow fan engine that was developed to power the AGM-129A Advanced Cruise Missile (ACM). It is an enhanced version of the F107-WR-101 used in the AGM-86B Air Launched Cruise Missile (ALCM). The engine is compact and lightweight because of the limited space available within the ACM. It incorporates radar absorbing material and other "low observable" or "stealth" technologies.
The X-36 is a small, remotely-piloted jet designed to fly without the traditional tail surfaces common on most aircraft. Built by McDonnell Douglas' Phantom Works division in St. Louis, Mo., the aircraft are 18 feet long with 10-foot wingspans, 3 feet high and weigh 1,270 pounds each. The aircraft are each powered by a Williams Research F112 turbofan engine that provides 700 pounds of thrust. A typical research flight lasted 35 to 45 minutes from takeoff to touchdown. A total of 31 successful research flights were flown from May 17, 1997, to November 12, 1997, amassing 15 hours and 38 minutes of flight time. The aircraft reached an altitude of 20,200 feet and a maximum angle of attack of 40 degrees.
