Difference between multrotor and fixed wing

We all know that in the UAV field is divided into multi-rotor and fixed-wing , this article will compare the following three aspects:


As for the definiton


A multirotor or multicopter is a rotorcraft with more than two rotors. An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed-pitch blades; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each.


A fixed-wing aircraft is an aircraft, such as an aeroplane, which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, in which the wings form a rotor mounted on a spinning shaft, and ornithopters, in which the wings flap in similar manner to a bird.


As for Dynamic principle


Multirotor and fixed-wing aircraft for the purposes of, in fact, the principle is the same to generate lift, it simply is the differential pressure and air flow up and down the wing shock effect caused by the air flow, but we know that the atmosphere increasing altitude, air density is getting smaller (after all, the existence of gravity) but we know that the atmosphere increasing altitude, the air density is getting smaller (after all, the existence of gravity) but we know that with the atmosphere elevation, the air density is getting smaller (after all, the presence of gravity) so that the larger the reactive force on the rotor, which lift more), but in the case of high altitude, the air density is low, even if the high rotor speed (due to the material strength limit, the so-called pneumatic shock impact, rotor speed is also limited), it is difficult to obtain greater thrust, the aircraft would be difficult to rise. Therefore rotorcraft flight altitude there is a certain limit. Lift fixed-wing flying up and down the main source of air pressure, fly faster compared to the greater lift, of course, he is also affected by aircraft or engine aerodynamic and structural characteristics of the speed increase can not be infinite.


As for power field


Multirotor has more electric motor drivers than the fixed-wing , so they need more capacity battery to provide power such as the

As for power field


Multirotor has more electric motor drivers than the fixed-wing , so they need more capacity battery to provide power such as the Gens ace 3s lipo batteries of 75C. But increased battery capacity , increase the quality of the aircraft , the aircraft is also a corresponding increase in power configuration , thus leading to the need for greater capacity of the battery can not be so infinite loop , and the lower the number , the more efficient the shaft .Resulting in many power are wasted. Therefore, multi-axis , the flight time and flight distance is limited , carrying equipment is also limited . However, electric wing as long as the rational design , can carry the same equipment, access to multi-axis more than the flight time and distance , but also to a certain height can be unpowered glider . It needs more time , a wide range of flight you can use oil moving fixed-wing and fixed-wing flight speed or some advantage. Like a large variety of military UAVs are now used to perform tasks across continents this mulrotor none(3s lipo voltage).


However everyone has their own interests ,no matter which type you choose ,just insist doing this and enjoy yourself!
