Abstract : The instrumentation of the Military Nomad N22B aircraft for flight testing was undertaken. Part of this instrumentation involved the measurement of aircraft pitch and yaw angles, and dynamic and static air pressures. These parameters were required to be measured in an undisturbed section of the air stream by mounting the instrumentation probe on a boom projecting forward from the nose of the aircraft. An earlier task undertaken was the design, stress analysis, and manufacture of the fittings, reinforcement, and stiffening of the nose baggage compartment of the Nomad to carry an existing boom for the initial flight trials. A brief description of this work is contained in Appendix I. While this boom met the requirements for rigidity and resonant frequency, it was relatively high in mass and transmitted uncomfortably high vibration loads into the airframe during some phases of the test programme. It was evident that a requirement existed for a lightweight, rigid boom.
