About the Jupiter HT1


The Airbus Helicopters H145 Jupiter (Jupiter HT1) provides advanced rotary wing flying training.


Like the H135, the H145 (Jupiter HT1) has introduced digital technology to the helicopter training programme.  The Juno and Jupiter cockpits include the very latest in Airbus Helicopters avionics, debuting the manufacturer’s new Helionix suite, which delivers enhanced safety and improved situational awareness.


Germany’s MBB and Japan’s Kawasaki joined forces in 1977 to design and build the BK117, a twin-engined multi-role helicopter notably equipped with twin clamshell loading doors in its aft fuselage.  The first prototype completed its maiden flight on June 13, 1979 and deliveries began in 1983. 

DASA and subsequently Eurocopter continued the co-operation with Kawasaki, producing a range of improved variants before embarking upon design of a new helicopter in 1997.  This combined the BK117’s rear section and cabin with the cockpit and forward section of the EC135, creating a new-generation BK117 equivalent that was designated EC145 (Jupiter HT1) from 1999. Further variants followed, including the dramatically redesigned EC145T2, which emerged in 2011 equipped with Arriel 2E turboshafts and a fenestron.  This aircraft forms the basis of the current production H145 (Jupiter HT1), which in its latest version includes Helionix avionics, for which Ascent is the first customer.  All three H145 Jupiter (Jupiter HT1) helicopters ordered against the UK MFTS requirement had been delivered by May 2017.
