The mobility of a quadrotor UAV is significantly affected by its aerodynamics. especially when the closely spaced rotors are applied in the multi-rotor system. This paper addresses the aerodynamic modeling of non-planar quadrotor UAV with various rotor spacing (1 d−2 d) and disk plane angle (0−50 deg). The inter-rotor interference and the power models are also proposed in ... https://parisnaturalfoodes.shop/product-category/lip-shimmer-champagne/
