Problems solved by technology
The amphibious hovercraft is heavy and relatively cumbersome, and cannot enter the air; while the amphibious wing-in-ground craft can only fly in a specific area, and the above two types of ships cannot be used for amphibious use
In view of this, amphibious hovercraft that can be used in water, land and sky appeared on the market. The wing installation angle is an important parameter of the amphibious hovercraft, which directly affects the performance of the amphibious hovercraft. The wing installation angle of the existing amphibious hovercraft adopts What is more important is the method of on-site testing, which requires repeated improvements and tests, which is time-consuming and laborious

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0025] Such as figure 1 As shown, the present invention provides a method for obtaining the wing installation angle of an amphibious hovercraft, comprising: Step 1, extracting and calculating the basic structural parameters of the amphibious hovercraft, specifically:
[0026] 1) Estimation of the total take-off weight of the amphibious hovercraft;
[0027] The main dimensions of the amphibious hovercraft are as follows:
[0028] Overall length: 760mm Overall width: 940mm
[0029] Wingspan: 350mm Apron volume: 0.42m2
[0030] The take-off weight of the amphibious hovercraft refers to the total weight at the beginning of the design-determined mission, where: W crew --The weight of the crew, the weight of three people is proposed to be used in this design; WF--the fuel weigh...

The invention discloses a method of obtaining the wing installing angle of a triphibian hovership. The method includes the steps that 1, basic structural parameters of the triphibian hovership are extracted and calculated; 2, modeling work is conducted, a triphibian hovership model is built up according to the basic structural parameters calculated in the step 1; 3, the triphibian hovership modelbuilt up in the step 2 is guided into Gambit software, and mesh generation is conducted on the triphibian hovership model; 4, the triphibian hovership model obtained after mesh generation is guided into Fluent software to conduct aerodynamic characteristics computational analysis; 5, the value of the attack angle when the lift-drag ratio reaches maximum is determined according to data obtained through computational analysis; 6, the wing installing angle is determined according to the obtained value of the attack angle in the step 5. The Fluent software is used for conducting aerodynamic characteristics computational analysis on the triphibian hovership to obtain the suitable wing installing angle.
Description
technical field [0001] The invention relates to the technical field of aircraft simulation calculation, in particular to a method for acquiring the wing installation angle of an amphibious hovercraft. Background technique [0002] At present, the mainstream amphibious ships in the world are amphibious hovercraft and wing-in-ground amphibious ships. The amphibious hovercraft is heavy and relatively cumbersome and cannot enter the air; while the amphibious wing-in-ground craft can only fly in a specific area. Neither of the above two types of ships can be used amphibiously. In view of this, amphibious hovercraft that can be used in water, land and sky appeared on the market. The wing installation angle is an important parameter of the amphibious hovercraft, which directly affects the performance of the amphibious hovercraft. The wing installation angle of the existing amphibious hovercraft adopts What is more important is the method of on-site testing, which requires repeated...
