A kind of aircraft electric power system
Technical field
The utility model is related to aircraft, the aircraft electric power system of especially a kind of replaceable power supply.
Background technology
Unmanned plane application technology is a upcoming technology.There are many new technologies on unmanned plane to be opened
Hair.Unmanned plane has very big potentiality to play a significant role in following logistics or monitoring activity.But still have some shortcomings.One
It is individual primary disadvantage is that the limitation of flight range, therefore a kind of technology should be developed to expand flight range.Allow unmanned plane during flying when
Between extension have many different methods.For example, unmanned plane can carry more or more preferable battery.This will extend the electricity of unmanned plane
Pond use time.However, it is not a nothing the matter to improve battery.Many companies are directed to improving the energy density of battery
Or the new battery technology of exploitation.However, in a short time, energy density does not have big improvement.If unmanned plane carries more
Battery, it can fly farther.But in a certain critical condition, the weight of battery becomes big, and flight range can decline again.So
The endurance of real improvement unmanned plane, in unmanned plane power technology is intelligently changed, power supply are can be only achieved by changing battery
Structure electrical cooperation between aircraft power fixed mount and mechanical engagement are most important.
