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.
