Times, due to high specific strength performance, excellent tensile strength and tensile modulus；Therefore the aerofoil profile undercarriage tool of the present embodiment
There is the advantages of high intensity, light weight.
There is a kind of undercarriage of the utility model the advantageous effect of the multi-rotor unmanned aerial vehicle of lift aerofoil profile to be：
1. during the unmanned plane during flying of the utility model, air-flow can carry out support support to aerofoil profile undercarriage during advance,
Further improve lift；That is aerofoil profile undercarriage Bionic Design will generate invalid resistance originally in flight course and increase simultaneously
The undercarriage optimization design of add weight improves unmanned plane during flying efficiency into the aerofoil profile undercarriage that can provide lift；This practicality is new
The aerofoil profile undercarriage of type so that it is not re-used as merely as the burden of unmanned plane, and aircraft aerofoil profile in flight course is risen and fallen
Frame can equally provide lift with wing, therefore from shape or in practicality, all have to the flight efficiency of aircraft very big
Promotion；
2. aerofoil profile undercarriage can folding and unfolding, in-flight occupied space smaller, resistance smaller, reliability higher；The utility model
Multi-rotor unmanned aerial vehicle novel in appearance, it is handsome in appearance, be a kind of completely new design.
