[0008] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0009] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0010] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0011] In the description of the embodiments of the present invention, "multiple" means at least 2.
[0012] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0013] Example:
[0014] Combined with Figure 1-3The present embodiment discloses a pulse turbine engine, comprising a plurality of combustion chamber assemblies 1, which are arranged circumferentially in a ring, the combustion chamber assembly 1 comprising a combustion chamber body 101, a tail exhaust pipe 102 is arranged at the bottom of the combustion chamber body 101, an intake pipe 103 is arranged at the top, the tail exhaust pipe 102 is connected to an exhaust main pipe 2, two U-shaped tubes 104 are also arranged at the top of the combustion chamber body 101, one of the U-shaped tubes 104 is connected to the intake pipe 103 on the current combustion chamber body 101, and the other U-shaped tube 104 is connected to the intake pipe 103 on the next combustion chamber body 101 behind the current combustion chamber body 101 in a clockwise direction; the intake pipe 103 is a conical wide mouth with an opening gradually increasing from bottom to top; an ignition device 106 is arranged on the outside of the combustion chamber body 101; and a fuel port 105 is arranged on the U-shaped tube 104.
[0015] In this embodiment, multiple combustion chamber assemblies form a ring, and the tail exhaust pipes are connected to the same exhaust main pipe. A turbine may or may not be installed in the exhaust main pipe. The intake pipe is configured to have a conical wide mouth, which can have a stamping effect. This embodiment forms a simple jet, which mainly has no moving parts and is easy to produce at a low cost. The combustion chamber uses a U-shaped tube instead of a blade or a piston, and compression and exhaust are carried out simultaneously. Multiple combustion chambers work by jetting in the form of pulses to make the jet stable.
