Flight Testing of Pioneer Bridges as Helicopter Slung Loads Using a CH-53G

Kurzfassung

Mobile pioneer bridges of different types were transported as helicopter slung loads in a test campaign in order to identify safe flight envelopes, handling qualities as well as practical handling instructions. The German Federal Armed Forces intend to standardize and to establish procedures of the external load transportation of pioneer bridges. Tests were carried out by means of a 20to CH-53G medium lift transport helicopter in close cooperation of the Wehrtechnische Dienststelle 61 (WTD 61, the German Armed Forces Technical and Airworthiness Center for Aircraft and Aeronautical Equipment), the Wehrtechnische Dienststelle 51 (WTD 51, German Armed Forces Technical Center for Pioneer and Troop Equipment) and the DLR (German Aerospace Center), where preparatory activities have been conducted by simulation in advance. The paper will discuss test preparations and results.
