Advanced Tandem Rotor Helicopter (ATRH) contract for JHL program

September 24, 2005 The U.S. Army has awarded a second contract to perform conceptual design and analysis of a vertical-takeoff-and-landing concept for the Joint Heavy Lift (JHL) program. One contract, worth US$3.4 million, goes to Boeing Phantom Works for its Advanced Tandem Rotor Helicopter (ATRH). Boeing proposed the ATRH in the Army's low-speed category, which is for vehicles that fly between 160 and 200 knots. As previously reported, the other contract, worth US$3.45 million, was awarded to the Bell Helicopter - Boeing Phantom Works team for the QuadTiltrotor (QTR) aircraft, which was entered in the high-speed category of 250 knots or more. The Boeing Advanced Tandem Rotor Helicopter exploits the system maturity, the extraordinary VTOL cargo-handling versatility and the unsurpassed maritime suitability of the tandem rotor platform, which uses two equally-sized rotors that spin in opposite directions for lift.
