Abstract

A frame assembly for an aerial system including a fuselage body and first and second rotor assemblies is described herein. The first and second rotor assemblies are coupled to the fuselage body by respective positioning assemblies. Each positioning assembly including a hinge assembly to enable the first and second rotor assemblies to pivot between a deployed position and a stowed position. A first positioning assembly including tapered positioning shaft. A second positioning assembly including a positioning sleeve having a tapered inner surface defining a cavity that is configure to receive the positioning shaft therein. The first positioning assembly being coupled to the second positioning assembly such that the first positioning assembly is rotatable about the rotor assembly rotational axis independent of the second rotor assembly.
