The Rolls-Royce Thrust Measuring Rig (TMR) was a pioneering vertical take-off and landing aircraft developed by Rolls-Royce in the 1950s. The TMR used two Nene turbojet engines mounted back-to-back horizontally within a steel framework raised upon four legs with castors for wheels. The TMR had no lifting surfaces (wings blades etc.) and was understandably nicknamed the Flying Bedstead.
