Embodiment Construction

[0040] specific implementation plan

[0041] Specific embodiments of the present invention are as follows:

[0042] (1) Use a high-speed camera to record the mouth features of the falcon when it is flying. After optimizing the recorded mouth features, draw the outer contour curve of the mouth longitudinal section on the coordinate paper. The specific drawing results are as follows Figure 4 shown (for reference only). graph paper

[0043] The above data are processed by the least square method to fit the contour curve equation of the longitudinal section of the falcon's beak, see the following formula for details:

[0044] x = 0.406 t + 7.742 t 0.5 y = 0.333 t - ...

Abstract

The invention relates to a partition-type engine cover outer plate, in particular to a bionic partition-type engine cover outer plate with an olecranon characteristic for a sportscar. The engine cover outer plate adopts a bionic design idea; an olecranon with favorable air adhesion decreasing and resistance reducing characteristic is used for a sportscar engine cover design, i.e., the outline curve of the engine cover outer plate is of a longitudinal-section outline bionic characteristic curve shape of the olecranon. The partition-type engine cover outer plate is capable of better achieving an enveloping effect on an engine and other parts in an engine compartment, is relatively good in heat insulation and sound insulation effects, and is simple in structure, streamline in modeling, beautiful in appearance and low in wind resistance coefficient.

Description

technical field [0001] The invention relates to a split engine cover, in particular to a bionic split engine cover outer panel with the characteristic of an olecranon. [0002] technical background [0003] Experiments show that the main resistance of sports car is air resistance when running at high speed. When the sports car is running at a speed of 80km / h, 60% of the power of the engine is used to overcome air resistance; when the sports car is running at a speed of 150km / h, its air resistance is 2-3 times the rolling resistance. Further studies have shown that air resistance is proportional to the square of the vehicle's degree, and the power consumed by the vehicle to overcome the air resistance is proportional to the cube of the vehicle's speed. It can be said that a car's aerodynamic performance directly affects its fuel economy. Empirical studies have shown that by optimizing the geometry of the hood of the vehicle body, the air resistance coefficient of the vehicle...
