Definitions
- the present invention relates to an aircraft having a jet engine, and more particularly to a technique for preventing bird strikes in an aircraft.
- Bird Strike is a phenomenon that is likely to occur when the flight speed is relatively low during altitude and low altitude during unstable flight taking off (just after landing and takeoff) or at low altitude. It is an important problem that must be solved for safe operation. Aircraft Bird Strike reported 1233 cases in Japan in 2006. For example, there are 118 cases at Tokyo International Airport and 94 cases at Kobe Airport. Losses due to engine damage and aircraft return to the airport due to these factors are said to be several hundred million yen each year in Japan alone. Various airlines and airports have taken various measures to prevent this, but there are currently no effective measures.
- Patent Document 1 discloses a cutting blade for cutting foreign matter invading into an inlet duct at a front end portion of the strut on the front side of the engine in an air intake port structure of a jet engine. The structure which provided this is disclosed.
- the technology disclosed in Patent Document 1 is, in an easy-to-understand manner, to make a bird “mince” to alleviate the impact on the strut, and not to prevent the bird strike itself. Absent.
- An object of the present invention is to provide an aircraft equipped with a jet engine that is effective in preventing bird strikes.
- the aircraft according to the present invention includes a bird knock-off device in a jet engine.
- the bird knocking device includes a bird knocking rod and a rotation driving device.
- the bird knocking rod is provided outside the jet engine at the front surface of the air inlet of the jet engine and rotates with a larger rotation area than the opening area of the air inlet of the jet engine.
- the rotational drive device rotationally drives the bird knocking rod.
- the jet engine is provided with the bird knock-off device, and this bird knock-off device is provided with the bird knock-off rod.
- a front surface of an air intake port of the engine is provided outside the jet engine, and rotates with a rotation area larger than an opening area of the air intake port of the jet engine. Therefore, birds that go to the air inlet of the jet engine are knocked out and removed by the rotating bird-throwing rod before being sucked into the air intake, preventing bird strikes. become.
- the bird knocking rod is driven to rotate by a rotation drive device.
- the rotary drive device may utilize the rotation of the jet engine and transmit it to the bird knocker, or may have a rotary drive source such as a motor and is provided separately from the jet engine. May be.
- a clutch mechanism is provided between the jet engine and the bird-throwing rod, and only when necessary Only, the rotation of the jet engine can be transmitted to the bird knocking-off rod by the clutch mechanism and can be rotated.
- FIG. 1 is a partially broken sectional view showing a part of an aircraft according to the present invention. It is the figure which looked at the aircraft shown in Drawing 1 from the air inhalation side. It is a figure which shows another embodiment which concerns on this invention. It is a fragmentary broken sectional view which shows the part about another embodiment of the aircraft which concerns on this invention.
- the aircraft according to the present invention has a jet engine 1.
- the jet engine 1 is attached to the lower surface of an aircraft wing 3 or the like.
- the overall image of the aircraft having the jet engine 1, the mounting structure of the jet engine 1, and the internal structure of the jet engine 1 are well known and need not be described.
- the jet engine 1 includes an air suction blade 12, a compressor 13, a combustion chamber (not shown), from an air suction port A side toward an exhaust port B on the opposite side.
- a turbine (not shown) and an exhaust port are sequentially arranged.
- the jet engine 1 includes a bird knocking device 2.
- the bird knocking device 2 includes a bird knocking rod 21 and a rotation driving device 22.
- the bird knocking rod 21 is provided outside the jet engine 1 in front of the air inlet A of the jet engine 1 and has a larger rotation area than the opening area of the air inlet A of the jet engine 1. , Rotate in the direction indicated by arrow F. That is, the bird knocking rod 21 is set to such a length that both ends thereof are located outside the outer peripheral surface of the outer cover 10 of the jet engine 1.
- the rotation driving device 22 rotationally drives the bird knocking rod 21 by the rotation shaft 23.
- the jet engine 1 is provided with the bird knock-off device 2.
- the bird knocking device 2 includes a bird knocking rod 21, which is provided outside the jet engine 1 on the front surface of the air inlet A of the jet engine 1.
- the engine 1 rotates with a larger rotation area than the opening area of the air inlet A of the engine 1. Therefore, the bird heading toward the air inlet A of the jet engine 1 is knocked out and removed by the rotating bird knocking rod 21 before being sucked into the inside thereof, thereby preventing bird strikes. Will be.
- the bird knocking rod 21 is driven to rotate by a rotation driving device 22.
- the rotary drive device 22 receives the rotation of the rotating body 11 of the jet engine 1 and transmits it to the bird knocking rod 21.
- a clutch mechanism is provided between the jet engine 1 and the bird knocking rod 21, and the rotation of the jet engine 1 is transmitted to the bird knocking rod 21 by the clutch mechanism only when necessary. This can be rotated.
- Bird Strike is a phenomenon that is likely to occur when take-off motion (sliding, immediately after take-off) or landing motion is relatively slow and at low altitudes. This phenomenon does not occur when you are.
- the rotation of the jet engine 1 is transmitted to the bird-tapping bar 21 only during the take-off operation or the landing operation by the clutch mechanism provided in the rotary drive device 22, and the jet engine 1 is transmitted at high altitude and stable flight.
- the clutch mechanism provided in the rotational drive device 22 is switched so that the rotation of the rotary drive device 22 is not transmitted to the bird knocking rod 21. Thereby, the energy loss by the bird knocking-down apparatus 2 and the fall of driving efficiency can be avoided.
- the rotation driving device 22 of the bird knocking device 2 is attached to the outer cover 10 of the jet engine 1 by the support 14 or the like.
- the bird knocking rod 21 may have a circular cross section, a square shape, a plate shape, a blade shape, or the like.
- a material having high strength, for example, a titanium alloy is preferable.
- the bird knocking bar 21 is singular. However, as shown in FIG. 3, it may be two or more.
- the rotary drive device 22 is provided separately from the rotary body 11 at a distance from the rotary body 11 on the front surface of the jet engine rotary body. 14 is suspended from the outer cover 10 of the jet engine 1.
- the rotation drive device 22 incorporates a rotation drive source such as a motor, and separates the rotation of the jet engine 1 to rotationally drive the bird knocking rod 21.
- the bird knocking device 2 does not become a rotational load of the jet engine 1, so that the efficiency is improved and the operation of the bird knocking device 2 can be performed separately from the jet engine 1. As a result, the influence on the flight driving system can be reduced.
