Abstract
The utility model provides a problem that a high efficiency screw for light -duty electronic aircraft, current light -duty electronic aircraft propeller work efficiency is low in main solution. It mainly comprises paddle and propeller hub. The propeller hub is a whole, and the paddle is 180 respectively and installs on the propeller hub. Furtherly, the quantity of paddle is 2, furtherly, the diameter D of paddle is 1.6 meters, furtherly, fixed pitch, the biggest chord length C is 0.15 meter, the propeller pitch angle theta of furtherly, 75% radius department is 16 degrees. The utility model discloses be suitable for cruising speed 100 -140Kmh, the rotational speed 1600rmin that cruises, maximum (top) speed 2400rmin, weight 480 -500Kg and lift -to -drag than 18 -20's light aircraft, the highest efficiency can reach 90.13%. The characteristics that have installation, inspection and easy maintenance. Can be applied to widely that agricultural plant protection is protected, technical field such as forest fire monitoring, aerial photographic, land survey and consequential loss aassessment.
Description
Technical field
The utility model relates to a kind of aircraft high efficiency screw propeller, and especially a kind of high efficiency screw propeller for light-weight electric aircraft, belongs to field of aerospace technology.
Background technology
Along with the development of global general-use Aerobiz, the development of various general-purpose aircraft is also increasing severely with day.Light-weight electric aircraft, because of features such as its acquisition cost are low, operation cost is low and easy to maintenance, is widely used in the tasks such as agriculture plant protection is protected, forest fire monitoring, aerophotography, land survey, consequential loss assessment.And common propeller works efficiency is low, causes electric airplane driving engine cannot reach the function of its reality in the work of reality, too increase energy consumption simultaneously.During in order to improve the boat of aircraft, screw propeller must have higher efficiency, enough pulling force, and ensures that screw propeller power requirement and engine power match.
Summary of the invention
For the ineffective problem of above-mentioned existing light-weight electric properller, the utility model provides a kind of high efficiency screw propeller for light-weight electric aircraft.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high efficiency screw propeller for light-weight electric aircraft, primarily of blade and propeller hub composition.Propeller hub is as a whole, and blade is arranged on propeller hub in 180 ° respectively.
Further, the quantity of blade is 2;
Further, the diameter D of blade is 1.6 meters;
Further, fixedpiston, maximum chord length C is 0.15 meter;
Further, the propeller pitch angle θ of 75% radius is 16 degree.
The beneficial effects of the utility model and feature: solve the problem that existing light-weight electric properller efficiency is generally on the low side preferably.Because it is rational in infrastructure, there is manufacture, operation cost is low; Install, check, easy to maintenance; Applied widely, the efficiency high of screw propeller, is widely used in the technical fields such as agriculture plant protection is protected, forest fire monitoring, aerophotography, land survey, consequential loss assessment.
