Description

  The present invention relates to a prime mover for an amphibious vehicle that includes wheels and wings and is capable of flying in the air in addition to traveling on the ground.

  It has long been thought to add wings and aerial propulsion means to an automobile, or to add wheel drive means to an aircraft to make an amphibious vehicle. In this case, if the air flight is the main and ground travel is additional, it is possible to travel on the ground by the propulsion means for air flight without driving the wheels particularly during ground travel, When the vehicle is substantially operated as a ground vehicle, wheel driving is necessary. The following Patent Document 1 describes a structure in which a propeller and a wheel for aerial flight are driven by a single engine. In the following Patent Documents 2, 3, and 4, the invention does not relate to driving a wheel. However, the wheels may be driven by an engine or an electric motor other than the power source for flying in the air. If a jet engine is used as an aerial flight power source, the wheel drive power source is inevitably a separate power source from the aerial flight power source.

  If the prime mover is an engine rather than an electric motor, it requires mechanical rotational power for starting. Therefore, an air-flight vehicle prime mover for an amphibious vehicle, which is impossible with an electric motor for the time being, requires a mechanical rotational power source for starting. Conventionally, an aircraft has been referred to as an engine starter as an engine starter. Motors or pneumatic motors that operate with compressed air, but where the weight reduction of the starter of the aerial flight prime mover is required, the amphibious vehicle is equipped with a prime mover for driving the wheel. It may be considered that the driving prime mover is used as a starting power source for the aerial flying prime mover. However, in an amphibious vehicle, the wheels and the aerial propulsion generating means such as propellers or jet engines are located far away from each other. In this case, the rotational power transmission mechanism that transmits the rotational power during that time increases in weight, and there is a risk that the weight further increases as compared with the case where a dedicated electric motor is provided for starting the aerial flight prime mover.

  In view of the above-described problems related to the starting of an aerial vehicle, the present invention relates to an amphibious vehicle that reduces the weight required to start the aerial vehicle as much as possible. It is an issue to provide.

  In order to solve the above problems, the present invention comprises a gas turbine that includes wheels and wings, and that is used as a prime mover for an amphibious vehicle capable of flying in the air in addition to running on the ground. A traveling motor generator coupled to the wheel for driving the wheel and driven by the wheel; a storage battery for supplying power to the traveling motor generator and being charged by the traveling motor generator; and an auxiliary engine And an auxiliary motor / generator driven by the auxiliary engine to charge the storage battery and supplied with electric power from the storage battery to drive the auxiliary engine, and the gas turbine is compressed in the auxiliary engine The present invention proposes a driving apparatus for an amphibious vehicle characterized by being started by compressed air.

  In this case, the compressed air may be compressed air generated in an intake air compression unit of the auxiliary engine by driving the auxiliary engine by the auxiliary motor generator, or the auxiliary engine may be generated by the auxiliary motor generator. Compressed air generated in the intake air compression portion of the auxiliary engine due to being driven and self-operating of the auxiliary engine, or generated in the intake air compression portion of the auxiliary engine due to self-operation of the auxiliary engine It may be compressed air.

  Alternatively, in order to solve the above-described problems, the present invention provides a gas turbine that includes a wheel and a wing and generates a thrust for aerial flight by using a motor for an amphibious vehicle capable of aerial flight in addition to traveling on the ground. A traveling motor generator coupled to the wheel for driving the wheel and driven by the wheel; and a storage battery for supplying power to the traveling motor generator and being charged by the traveling motor generator An auxiliary engine; an auxiliary motor generator driven by the auxiliary engine to charge the storage battery and supplied with electric power from the storage battery to drive the auxiliary engine; and at least one of the auxiliary motor generator and the auxiliary engine An auxiliary compressor driven by the gas turbine, wherein the gas turbine is started by compressed air compressed in the auxiliary compressor. It is intended to propose a driving force generator of that land and air amphibious vehicle.

  In this case, the compressed air is compressed air generated in the auxiliary compressor when the auxiliary compressor is driven by the auxiliary motor generator, or the auxiliary compressor is connected to the auxiliary motor generator and the auxiliary motor generator. Compressed air generated in the auxiliary compressor by being driven by the auxiliary engine, or compressed air generated in the auxiliary compressor by the auxiliary compressor being driven by the auxiliary engine. It may be.

  In any case, the auxiliary engine may be a gas turbine or a reciprocating engine.

  As a prime mover for an amphibious vehicle that has wheels and wings and can fly in the air in addition to running on the ground, a prime mover that drives the wheels is necessary, but first of all, the wheels are electrically driven and connected to the wheels The traveling motor / generator that drives the wheel and is driven by the wheel, and the storage battery that supplies power to the traveling motor / generator and is charged by the traveling motor / generator. This means that the amphibious vehicle is an electric vehicle when traveling on the ground. One limitation in the performance of an electric vehicle is the limit of the distance that can be traveled without being charged by an external power source. Increasing this is one of the major issues related to the improvement of electric vehicles. As one means for solving this problem, it is considered to provide power generation means in the vehicle itself, one of which is an auxiliary engine and auxiliary power generation that is driven by the auxiliary engine and charges the storage battery. However, since the auxiliary engine requires a starting rotational power source, the auxiliary generator is a motor generator, and when starting the auxiliary engine, power is supplied from the storage battery to the auxiliary motor generator. It is conceivable to start the auxiliary engine by operating the auxiliary motor generator as an electric motor.

  As described above, it is assumed that the drive on the ground of an amphibious vehicle is an electric drive by a storage battery and a traveling motor generator, and the auxiliary motor generator and the auxiliary engine are provided mainly for the purpose of increasing the traveling distance. Based on the structure, if the aerial flight prime mover that generates thrust for aerial flight is a gas turbine, unlike a reciprocating engine, the gas turbine is smoothly accelerated by blowing compressed air onto the rotor, and its rotational speed is Since the engine is started when the value exceeds a certain value, it is considered that compressed air is generated by using the storage battery, the auxiliary motor generator, and the auxiliary engine, thereby starting the aerial flight gas turbine.

  First, paying attention to the fact that the engine includes an intake air compression section, the auxiliary motor generator is operated as an electric motor using the storage battery as a power source to drive the auxiliary engine, and the auxiliary engine is compressed by the intake air compression. Let's consider generating compressed air for starting a gas turbine for aerial flight by operating as a compressor that compresses air in a section.

  In this case, if the fuel supply system of the auxiliary engine is not operated, the compressed air is compressed air generated when the auxiliary engine is driven by the auxiliary motor generator, but the fuel supply system of the auxiliary engine is operated appropriately. In this case, the compressed air becomes compressed air generated by the auxiliary engine being driven by the auxiliary motor generator and the self-operation of the auxiliary engine, and the output of the auxiliary motor generator is further adjusted in accordance with the operation of the fuel supply system. If extinguished, the compressed air can be made into compressed air obtained by extracting a part of the intake air compressed by the self-operation of the auxiliary engine.

  Alternatively, if an auxiliary compressor driven by at least one of the auxiliary motor generator and the auxiliary engine is provided in addition to the auxiliary motor generator and the auxiliary engine, the battery on the ground can drive the amphibious vehicle. Based on the premise that an auxiliary motor generator and an auxiliary engine are provided mainly for the purpose of increasing the travel distance of the motor driven by the motor generator for traveling, the auxiliary which requires only a small addition in weight Compressed air for starting an aerial flight gas turbine can be obtained simply by providing a compressor.

  In this case, if the fuel supply system of the auxiliary engine is not operated, the compressed air is compressed air generated by driving the auxiliary compressor by the auxiliary motor generator. When operated properly, the compressed air becomes compressed air generated by driving the auxiliary compressor by the auxiliary motor generator and the auxiliary engine, and further, the auxiliary motor power generation is performed in accordance with the operation of the fuel supply system of the auxiliary engine. If the output of the machine is extinguished, the compressed air becomes compressed air generated when the auxiliary compressor is driven by the auxiliary engine.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram illustrating an example of an apparatus for driving an amphibious vehicle according to the present invention in which an auxiliary compressor is provided in addition to an auxiliary engine.

  In FIG. 1, 10 is a gas that has a wheel and a wing, but is not shown as an external appearance, and that generates thrust for aerial flight of an amphibious vehicle capable of flying in the air in addition to ground running. A turbine, which in the illustrated embodiment is a turbofan engine. In the turbofan engine 10, the intake air compressed by the inner peripheral portion of the fan 12 and the axial flow type compressor 14 in the illustrated embodiment is heated by the combustion of fuel in the combustor 16, and the high temperature and high pressure generated thereby. The compressor 14 is driven by the first stage turbine 18 driven by the combustion gas of the gas, the fan 12 is driven by the subsequent second stage turbine 20, and the gas flow ejected from the second stage turbine 20 via the annular nozzle 22; The air urged by the outer peripheral portion of the rotating fan 12 generates a thrust by the air flow discharged through the annular nozzle 24. On the other hand, 26 is a motor generator for running an amphibious vehicle, which is connected to a wheel 28 and drives the wheel when the vehicle is accelerated, and is driven by the wheel when the vehicle is decelerated. Reference numeral 30 denotes a storage battery that supplies electric power to the traveling motor generator 26 when the vehicle is accelerating, and is charged by the traveling motor generator 26 when the vehicle is traveling at a reduced speed.

  With only the above configuration, the distance that the vehicle can travel on the ground is limited by the storage capacity of the storage battery 30. In order to alleviate this restriction and increase the distance that the vehicle can travel on the ground, an auxiliary motor generator 32 and an auxiliary engine 34 that drives it are provided. In the embodiment of FIG. 1, the auxiliary engine 34 is a gas turbine, drives the auxiliary motor generator 32, charges the storage battery 30 at any time with the electric power generated thereby, and the vehicle in comparison with the storage capacity of the storage battery 30. The distance that can be traveled on the ground is increased.

In the turbine 34, the compressed air generated by driving the compressor portion 36 is guided to the inlet portion of the axial flow compressor 14 in the illustrated embodiment by an air conduit 38, and the compressor 14 is supplied from the nozzle 40. The gas turbine 10 is sprayed on the rotor blades and is rotationally driven for starting.

  In this case, when generating the compressed air for starting the gas turbine 10, if the fuel supply system (not shown) is not operated in the auxiliary engine 34, the compressed air is supplied to the auxiliary engine 34, particularly the compressor. Compressed air generated when the part 36 is driven by the auxiliary motor / generator 32 will be compressed. If the fuel supply system of the auxiliary engine 34 is operated appropriately, the auxiliary engine 34 will generate compressed air. The compressor unit 36 is driven by the auxiliary motor generator 32, and the auxiliary engine 34 is driven by itself, that is, the compressor unit 36 is driven by the turbine unit 42. Compressed air generated by Furthermore, if the output of the auxiliary motor / generator 32 is extinguished in accordance with the operation of the fuel supply system of the auxiliary engine 34, the compressed air for starting the turbine 10 is generated in the intake compression section by the self-operation of the auxiliary engine 34. It becomes the compressed air which took out a part of compressed intake air.

  FIG. 2 is a schematic view similar to FIG. 1 showing another embodiment of the present invention in which a part of the prime mover for the amphibious vehicle shown in FIG. 1 is modified. 2, parts corresponding to those shown in FIG. 1 are indicated by the same reference numerals as in FIG. 1, and operate in the same manner as in FIG.

  In this embodiment, the starting compressed air of the turbine 10 is separated from the auxiliary engine 44 and is compressed by an auxiliary compressor 46 driven by at least one of the auxiliary motor generator 32 and the auxiliary engine 44. It has come to be. In this embodiment, the auxiliary engine 44 is a reciprocating engine. Also in this case, the compressed air for starting the turbine 10 is driven by the auxiliary motor generator 32 unless the fuel supply system (not shown) is operated in the auxiliary engine 44. However, if the fuel supply system of the auxiliary engine 44 is appropriately operated, the compressed air is driven by the auxiliary motor generator 32 and the auxiliary compressor 46 becomes the compressed air generated by being driven by the auxiliary engine 44. Further, if the output of the auxiliary motor generator 32 is extinguished in accordance with the operation of the fuel supply system of the auxiliary engine 44, the auxiliary compressor 46 is driven by the auxiliary engine 44 as compressed air for starting the turbine 10. Compressed air due to

  Thus, the amphibious vehicle is propelled by the gas turbine 10 in the aerial flight, and is electrically driven by the motor generator 26 in the ground travel, so that the travelable distance in the ground travel is increased. When the storage battery 30 is auxiliary charged by the auxiliary motor generator 32 and the auxiliary engine 34 or 44, the starting means for the aerial flight gas turbine 10 with only a slight weight addition to the auxiliary charging means.
