The Rolls-Royce RB.162 is a lightweight British turbojet engine produced by Rolls-Royce Limited. Developed in the early 1960s, it was specially designed for use as a lift engine for VTOL aircraft but was also used in a later variant of the Hawker Siddeley Trident airliner as an auxiliary boost engine. A smaller related variant, the RB.181 remained a design project only, as did a turbofan version designated RB.175.
Design and development
The RB.162 was designed to meet an anticipated need for a lift engine to power VTOL aircraft with the emphasis on simplicity, durability and lightweight construction. Development costs were shared by Britain, France and Germany after signing a joint
French francs (1970 value, or 94 million euros in 2022 values) between 1960 and 1966 for the Mirage IIIV.[4]
Development for the Trident
In 1966
Mediterranean destinations. After a plan to operate a mixed fleet of Boeing 727 and 737 aircraft was not approved by the British Government[5] Hawker Siddeley offered BEA a stretched and improved performance version of the Trident that they were already operating. This variant, the Trident 3B, used, in addition to its three Rolls-Royce Spey turbofan engines, a centrally mounted RB.162-86 which was used for takeoff and climb in the hot prevailing conditions of the Mediterranean area. The 'boost' engine was shut down for cruising flight. Some conversion was needed for the change from vertical to horizontal installation. With the RB.162 fitted the Trident 3B had a 15% increase in thrust over the earlier variants for an engine weight penalty of only 5%.[6]
