Wind Tunnel Test of a C-18 Aircraft Modified with the Advanced Range Instrumentation Aircraft Radome

Abstract

The Air Force intends to modify Boeing 707-320C aircraft (Air Force designation, C-18) with the large blunt nosed Advanced Range Instrumentation Aircraft (ARIA) radome formerly installed on EC-135 aircraft. This modification will significantly increase fuselage area forward of the aircraft center of gravity and is expected to reduce longitudinal and directional stability, and increase drag. These anticipated aerodynamic changes were evaluated from data gathered on a modified (ARIA) gathered on a modified (ARIA) and unmodified (BASIC) 1/100 scale model C-18 tested in the AFIT five foot low speed wind tunnel.
