  • Lunar area observation and communication system and bounce device
    The present application relates to area observation, in particular to a lunar area observation and communication system and a bouncing device. Observation of the lunar region is of great significance. Since the United States achieved the moon landing in the last century, more and more countries have begun to explore the moon. Because there is no atmosphere on the lunar surface, aircraft cannot fly on the lunar surface, so only close-range regional exploration can be performed by lunar vehicles month. The return cabin carries the lunar rover to the moon and communicates with the lunar rover through the communication system ...
  • Manufacturing method for measuring angle of aileron deflection of aircraft
    The invention relates to aeronautical equipment, in particular to a protractor for measuring the aileron deflection of an aircraft. Aileron refers to a small piece of movable airfoil installed outside the trailing edge of the wing tip. For the main rudder surface of the aircraft, the rolling moment generated by the pilots' differential deflection of the left and right ailerons can make the aircraft roll. According to the repair requirements, the aileron's swing and deflection need to be measured after special inspection and maintenance to ensure that its deflection is within a fixed range ...
  • Method and process for enhancing surface resistance reduction of drone body
    The invention relates to a method for surface enhancement and drag reduction, and in particular to a method for surface enhancement and drag reduction of a drone body. Traditional foam airframe drones are popular because of the low cost of model production, easy production, and low price. However, due to the low density of the surface material of the foam airframe, the material is relatively fragile, and the wind resistance during flight is relatively large. When the aircraft takes off and landed violently and landed, the body will receive different degrees of ...
