BAE Systems, a transatlantic defence and aerospace company responsible for the manufacture of the Eurofighter Typhoon, has been
sourcing products from Industrial Gas Springs (IGS) for the twin-engine, multi-role, canard-delta wing strike fighter aircraft since
production commenced in 2001.
IGS struts are utilised in various locations on the Eurofighter Typhoon aircraft including windscreen, ladder, ladder door, avionic bay door (twin
seat only), MDP door and AC external power access door units.
Strict guidelines had to be met in specifying materials and equipment for the manufacture of Typhoon. For example, the gas struts had to be
designed to meet the vigorous requirements of the Typhoon
environmental handbook that included the ability to withstand
extreme conditions as defined in MIL-STD-810D. The IGS
units were manufactured from high-grade materials
and tested to the same levels as fully operational
flight standard equipment.
“Further differentiators for us when selecting the
gas springs were the nil maintenance, effective
performance and lightweight properties of the struts.
The ability to operate effectively over the entire ground
operating temperature range -31°C to +90°C was also
vital,” says Aidan Lowe, senior systems engineer, Typhoon
General Systems.
“Our technical team found the company demonstrated a
supportive ‘can do’ attitude regarding specific requirements and
offered excellent bespoke designs. Another vital aspect was their ability to
rapidly prototype new design iterations, allowing the team to refine the design
solution in a short timescale”, explains Aidan.
