Nohab Flygmotorfabriker AB was founded in Trollhättan, Sweden, in 1930 to produce aircraft engines for the Swedish Board of Aviation. As the name of the company indicates it was a subsidiary to NOHAB. In 1937 it became a part of the newly founded SAAB but already in 1941 Volvo acquired a majority of the stock and the name was changed to Svenska Flygmotor AB (SFA), and later on Volvo Flygmotor.
Since the 1950s the company have been the major engine supplier to the Swedish Air Force. The Volvo Aero Group has 3,600 employees and in 2003 had total sales of 0.9 billion euros. Today Volvo Aero is a partner in more than ten commercial engine programmes. Components from Volvo Aero are installed in more than 90% of all large commercial aircraft engines sold.
Aircraft engines and components
Volvo Aero is a supplier of single-engine systems for military aircraft. These have largely been in partnership with other engine manufacturers, such as the RM1 (de Havilland Goblin) for the Saab 21R, RM2 (de Havilland Ghost) for the Saab J29, RM5 and RM6 (Rolls-Royce Avon) for the Saab 32 Lansen, the RM6B for the Saab 35 Draken, and the RM8 (Pratt & Whitney JT8D) for the Saab 37 Viggen. The Saab JAS 39 Gripen's RM12 engine is a derivative of the General Electric F404.
Svenska Flygmotor also designed the B42, horizontally-opposed four-cylinder engine, intended for the SAAB Safir. However, SAAB decided on using engines from de Havilland and Lycoming for the Safir. In the end the B42 came to power the Infanterikanonvagn 103 assault gun. A follow-up called B44 powered the Pansarbandvagn 301 armoured personnel carrier.
Volvo Aero delivers engine components, mainly complex engine structures like turbine exhaust casings, turbine mid frames, LPT cases, compressor housings, LPT shafts, vanes, and large rotating parts.
Engine maintenance and service
Volvo Aero also has a facility in Trollhättan where they did maintenance on aircraft engines and stationary gas turbines. The aircraft engines are Pratt & Whitney Canada PW100 and TFE-731 engines. The Stationary gas turbines is General Electric LM1600 engine, and the DR990, which Volvo bought the OEM responsibility from Dresser Rand.
Volvo Aero manufactures combustion chambers, nozzles and turbines for commercial launch vehicles.
The company have produced the F-series hydraulic motors under the Volvo Flygmotor, "Volvo Hydraulics" and VOAC brands. The main feature for these products is the spherical pistons with laminated segment. This technology give the possibility to obtain a large angle (40°) between the shaft and the cylinder barrel.
Volvo Aero subsidiaries are located in the United States and Norway, in addition to Volvo's home country, Sweden. The Norwegian plant, in Kongsberg, is the former Norsk Jetmotor, itself formerly a part of Kongsberg Våpenfabrikk.
