Rolls-Royce RB.162
The Rolls- Royce RB.162 is a simply constructed lightweight jet engine of the 1960s, which was mainly used as a lift engine in VTOL aircraft. As a further development of the RB.108 it belongs to the second generation of the lift engines from Rolls -Royce. Funding was provided by the Governments of France, Great Britain, the Federal Republic of Germany and the Rolls- Royce Ltd..
History
The objective in the construction of RB.162 was to achieve a doubling of the thrust, while maintaining the weight of the RB.108 at reduced cost by half. These objectives were achieved. The major development began in September 1959, the first run took place in November 1961. The particularly important in Hubtriebwerken acceleration time from idle to full thrust is only 1 1/2 seconds.
The RB.162 is considered the first lift engine, which made possible the design and construction of operational V/STOL-Kampf- and transport aircraft. These included the Mirage IIIV and Dornier Do 31 While the RB.108 the thrust - weight ratio was still at 1:8, this was improved to 1:16 when RB.162.
Construction
The RB.162 is a Einwellentriebwerk with a six-stage axial compressor and a single stage turbine. For the compressor blades ( with the exception of the first stage ) and for the two-part housing was largely glass fiber reinforced plastic (FRP ) are used, since the highest compressor temperature remained below 200 ° C.
Variants
- RB.162 - 1 derived for Mirage IIIV, 10 % as bleed air
- RB :162 -4: for the Do -31 prototype, no bleed air
- RB.162 -31: for Mirage IIIV - development, 25 % higher thrust
- RB.175: Planned version with additional front fan and about double thrust, not realized
Use
- Mirage IIIV
- Dornier Do 31
- VFW - Fokker VAK 191B
- Hawker Siddeley Trident 3B at as a booster engine, which was only temporarily put into operation
