Embodiment approach 1
[0035] Embodiment 1: The material of the vehicle body model is cast iron. The power supply is a lithium battery. The height of guide rail 6 is apart from tank 0.4m, and the quality of counterweight 14 is 5 kilograms. The drag speed V obtained by the vehicle model h =2.5m / s, vertical water entry speed V v =2.8m / s.
Embodiment approach 2
[0036] Embodiment two: Embodiment two is basically the same as Embodiment one, and differs from Embodiment 1 in that the quality of the counterweight 14 and the height of the guide rail 6 are changed, respectively: the height of the guide rail 6 is 0.6m apart from the water tank, and the height of the counterweight 14 The mass is 8 kg. The drag speed V obtained by the vehicle model h =3.2m / s, vertical water entry speed V v = 3.43m / s.

A navigation body water-entry experiment device having convected velocity comprises a water tank containing water and a releasing device, wherein a motion platform of the releasing device is a rectangular platform, a switch and a power supply are arranged on the motion platform, a travel switch is arranged at the front end of the motion platform, a guide rail is arranged above the water tank, a stop bolt is arranged at the front portion of the guide rail, a contact of the travel switch is a contact which can move on the guide rail and can be fixed at any position, a sliding bearing is installed below the motion platform and is supported on the guide rail, a model hanging frame is a long electromagnet, the upper end of the electromagnet is fixed below the motion platform, the lower end of the electromagnet is a navigation body model hanging end, the power supply makes the switch and the travel switch in serial connection with the electromagnet of the model hanging frame through a lead, and a balance weight is connected to the front end of the motion platform through a hauling cable. The navigation body water-entry experiment device has the advantages that the horizonal convected velocity and vertical speed of a navigation body model are adjustable, the operation is convenient, the reliability is high, the cost is low, and the experiment efficiency is higher. The electromagnet releases the navigation body model, mechanical disturbance is smaller, and the experimental result confidence level is higher.
Description
technical field [0001] The invention belongs to the technical field of water entry experiment devices for a vehicle, in particular to a water entry test device for a vehicle with implicated speed. Background technique [0002] The water entry experiment of the vehicle body model is of great significance in engineering applications. The water entry of the vehicle body generally includes oblique water entry, vertical water entry, and re-entry of the trans-medium aircraft. For example, the water entry of an air-dropped torpedo not only has a vertical speed, but also has a horizontal implicated speed. A large number of model water entry experiments are required to carry out engineering experimental research. [0003] In the prior art, the water entry experiment of the vehicle body model is mainly a vertical water entry experiment. For the water entry problem of the air-dropped torpedo that has a horizontal speed involved in the water entry experiment, a special design of the wat...
