'Space airbags' may help protect helicopters in emergency
London:
A technique used in many NASA Mars rovers could
be used to protect helicopters in emergency landings,
by placing airbags on the underside of the choppers.
Several of NASA Mars rovers have successfully landed
on Mars, protected from impact with the ground by
sophisticated airbags. Now, according to a report
in New Scientist, the helicopter manufacturer Bell
Helicopter based in Fort Worth, Texas, believes the
same technique could be used to protect helicopters
in emergency landings. The bags would be fitted to
the underside of a helicopter and deployed only when
the vehicle is about to hit the ground at too high
a velocity. They would be able to help the helicopter
in a crash landing, and keep a craft afloat if it
ditches in the sea. According to the company, the
bags are also designed to reinflate after impact to
act as flotation devices should the helicopter ditch
in water.
