The Vertical Flight Society (VFS) is holding its inaugural Design-Build-Vertical Flight (DBVF) student competition. VFS is tasking teams with designing, manufacturing, and flight testing an urban air mobility (UAM) aircraft with a maximum weight of 20 lbs and the largest dimension of 6.5 ft. This report covers the design, analysis, manufacturing, and testing for the OSU DBVF team’s aircraft. Through analysis of the competition and considerations from previous years teams, the OSU team preliminary vehicle has converged to a compound-type helicopter for efficient high-speed flight and best predicted score in all competition courses. The team's design has a main rotor and an embedded tail rotor that will enable hovering flight while the main rotor coupled with small fixed-wings will provide lift for cruise flight. Forward thrust and counter rotor-torque will be provided by a twin-propellers assembly on the wings. Technical analysis helped improve the design with regards to weight and performance. The team recieved the "Most Creative Award for the team’s lift-offset single rotor heli"
