Abstract:

It is the purpose of this report to determine the aerodynamic characteristics of each of the component parts of the XC-120 airplane. No attempt is made in this report to determine the characteristics of the complete airplane. For convenience the report is divided into three parts. Part 1 consists of general information and includes a complete summary of the physical and aerodynamic characteristics of the component parts. Part 2 presents the calculations and explains in detail the method of calculation of the aerodynamic characteristics, and Part 3 presents a complete list of all references. Power on conditions refer to military power only and flaps down condition is for 40 deg flap deflection only. The XC-120 airplane is a modified version of the C-119B airplane and features a detachable cargo compartment with both front and rear loading provisions, which is called the pack. The compartment provided for pilot and crew members is of course not detachable and is designated crew nacelle. The fuselage consists of the pack plus the crew nacelle. Due to the peculiar configuration required for the detachable pack, a quadricycle landing gear is required. Wing incidence has been increased from 3 deg C-119B to 7 deg at the wing root chord.
