Abstract
Engine 30 has a compression fan 36 coaxially mounted with reaction member 38. Casing 32 extends around reaction member 38 to form volute 52 and extends to turbine wheel 54 which is connected to compression fan 36 via axle 40. Reaction member 38 comprises vanes 60, flame grid 62 and supporting members in the form of side casings 64. A mixture of fuel and air enters engine 30 via inlets 34. The mixture is drawn into compression fan 36 which causes an increase in the pressure of the mixture. From the compression fan 36 the mixture is directed towards the reaction member 38. Because the compression fan 36 is rotating in a first sense and the reaction member 38 is rotating in a second sense, the velocity of the fuel and air mixture entering the reaction member 38, relative to the reaction member 38, is approximately the sum of the external rim velocity of the compression fan 36 and the internal rim velocity of the reaction member 36. The mixture is burnt within the reaction member 38 and the vectored gases cause the rotation of the reaction member 38 in the second sense.
