Bell Griffin HT1

Role

Used for general-handling flying, underslung-load carrying, night-vision goggle training, procedural instrument flying, formation flying, low-flying navigation and an introduction to tactical employment.

Details

The Griffin HT1 is used as an advanced flying-training helicopter at the Defence Helicopter Flying School (DHFS) at RAF Shawbury, in Shropshire, and the Search and Rescue Training Unit (SARTU) at RAF Valley, in Anglesey. The Griffin HT1 is a military twin-engined helicopter derived from the civilian Bell Textron 412EP helicopter and is powered by two Pratt & Whitney turboshafts rated at 1800shp. The aircraft has an advanced, composite material, fourblade main rotor system, and pendulum dampers on the rotor hub to reduce vibrations at higher cruise speeds. The composite main-blades can be interchanged and folded easily for storage.

With a cruising speed of 120kts (138mph) and an endurance of almost 3 hours which makes it ideally suited for advanced helicopter training, the Griffin HT1 is ideally suited for Multi-engine Advanced Rotary Wing (MEARW) training, which is completed at No 60(R) Squadron at RAF Shawbury. The syllabus includes general-handling flying, underslung-load carrying, night-vision goggle training, procedural instrument flying, formation flying, low-flying navigation and an introduction to tactical employment, including operations from confined areas. A short SAR-procedures course, which includes elements of mountain flying and maritime rescue winching, is conducted at RAF Valley. However, students who are finally streamed for SAR flying duties on completion of their advanced helicopter training return to SARTU to complete an extended SAR course prior to joining the Sea King Operational Conversion Unit at RAF St Mawgan.

In addition to pilot training, the Griffin is used for crewman training: a very important and integral part of multi-crew operations.
