Definitions
- Jet turbine engines used by aeromodellers suffer a number of inconveniences They must be run up initially using compressed air to rotate the turbine
- the injectors must be preheated usually by propane
- the fuel is supplied by an electric fuel pump which requires the aircraft to carry a speed controller and battery to control engine speed
- Some conventional engines require oil to be mixed with the fuel so that when the engine is shut down, and still very hot, there is no lubrication
- Others carry a separate oil supply with its inherent penalties of weight and complexity
- a turbine engine having a compressor towards the front and a turbine towards the rear and connected by a shaft, an electric motor and/or generator having a rotor mounted on the shaft preferably between the compressor and the turbine
- a small starter battery is suitable to run up a model engine and, with any necessary controller, is convenient to carry or may be mounted on board, if desired Once the engine is running, the starter battery and/or the receiver battery may be charged from the generator
- the combustion chamber is preferably located behind the turbine, a first passage connecting an outlet of the compressor to an inlet of the combustion chamber, and a second passage connecting the outlet of the combustion chamber to an inlet of the turbine
- the electric motor and/or generator preferably has a static armature
- the rotor comprises at least one permanent magnet, which may be mounted on an impeller of the compressor
- the rotor is in the form of a disc mounted directly on the shaft
- the disc may be a conducting metal, e g copper, so that the motor and/or generator is in the form of an induction motor and/or generator
- a turbine engine having a compressor towards the front, a turbine towards the rear and connected to the compressor by a shaft, and a fuel pump having a rotor mounted on the shaft for rotation therewith
- the speed of the engine can be controlled by a valve and a servo
- the servo can be powered by the aircraft's receiver battery
- the rotor preferably has a central inlet and radially extending passages, the rotor being contained by a casing providing a fuel outlet
- the fuel outlet is preferably connected via a fuel delivery passage to one or more injectors directed into the combustion chamber, a bypass valve also being connected to the fuel delivery passage to control flow rate of fuel delivered to the ⁇ njector(s)
- the fuel pump also delivers fuel via a regulator valve to cool one or more bearings on which the shaft is mounted
- a turbine engine having a compressor towards the front and a turbine towards the rear and connected by a shaft, the compressor and the turbine being connected by a combustion chamber into which fuel is injected and burnt, at least one injector for injecting fuel into the combustion chamber, which injector has a helical passage to impart vortex motion to fuel injected into the chamber
- the vortex motion facilitates the injected fuel dividing sufficiently finely, e g to a vapour, that ignition can be obtained without preheating
- Figure 1 is a longitudinal cross section through a micro jet turbine engine having a fuel pump embodying an aspect of the invention
- Figure 2 is an enlarged cross section of the fuel pump
- Figure 3 is a transverse cross section of the fuel pump

- the casing 10 is mounted on a compressor diffuser 12 by a plate 14 and spacers 16
- An external case 18 is connected to the diffuser 12 and defines a passage from an annular outlet 20 of the compressor to a toroidal combustion chamber 22 walls 24 of which are perforated to allow air from the compressor to enter
- Fuel is injected into the combustion chamber 22 by a plurality of injectors 26, which extend through the casing 18, and ignited initially by a spark plug 28 Only one of the injectors is shown in the drawings
- Exhaust gasses from the combustion chamber enter an annular inlet 30 of the turbine 4 and leave via an exhaust 32 which passes through a rear plate 34 of the casing
- a rotor 36 of a fuel pump 37 is mounted on the shaft 6 for rotation therewith
- the pump has a stator 38 within which the stator 38
- the pump inlet 40 is connected to a fuel tank 56 via a filter 58

- a set of printed coils 74 is mounted on a stator 76 disposed in the casing 10
- the coil extends into an air gap 78 in the rotor so that a magnetic circuit including the permanent magnets passes through the coils

- An injector 26 is illustrated in Figure 7
- the injector has a body 86
- Fuel delivered from the fuel pump 37 passes through a passage 88 to a nozzle 90 which is threadedly mounted on the body
- the fuel leaves the nozzle under pressure via a jet orifice 92
- a section 94 of the passage 88 approaching the orifice 92 is conical and forms a seat for a conical surface 96 of a plug 98 which is urged into sealing engagement with the conical section by a compression spring 100
- Spiral grooves 102 in the conical surface 96 of the plug provide spiral passages through which the fuel passes to give a vortex motion to the fuel injected through the orifice 92
