Martin-Baker
Martin-Baker Aircraft is a manufacturer of
aircraft seats and is the oldest existing maker of
ejection seats.The company's headquarters are in
Higher Denham,
Buckinghamshire,
UK. It started as the Martin Baker Aircraft Company, founded in
1929 by James Martin (
September 11,
1893 -
January 5,
1981) and Valentine Baker (
August 24,
1888 -
September 12,
1942).
Martin-Baker produced several
prototype military aircraft during the
Second World War, although none ever entered production. These designs included:
*
Martin-Baker M.B.1*
Martin-Baker M.B.2*
Martin-Baker M.B.3*
Martin-Baker M.B.5*
Martin-Baker M.B.6, (WW2 jet fighter project with swing-arm, 0/0 spring-loaded ejection seat)
*
Martin-Baker M.B.7,
Black Bess (postwarinterceptor/high-speed test aircraft concept). Small flight models made but concept cancelled in 1947.
Throughout the war it manufactured aircraft components including armoured aircraft seats for
Supermarine Spitfires. In
1944 the company was approached by the
Ministry of Aircraft Production to investigate providing high speed fighter aircraft pilots with assistance in bailing out.

Martin-baker started to investigate ejection seats from 1934 onward, several years before Germany (1938) and Sweden. The company concluded that an explosive-driven ejection seat was the best solution. Studies found the limits of upward acceleration which the human body could stand and included experiments on a volunteer, Bernard Lynch, who was a
fitter at the factory. Their first seat was successfully live tested by Bert Lynch on
July 24,
1946, who ejected from a
Gloster Meteor travelling at 320 mph (510 km/h)
IAS at 8,000 feet (2,500 m) over Chalgrove airfield in
Oxfordshire.
The first use of an ejector seat in a real situation by a British pilot involved the
Armstrong Whitworth A.W.52 flying wing experimental aircraft in May 1949.
Martin-Baker has supplied approximately 69,000 ejection seats of which 19,000 are currently in service. Around 7,000 - 10% of the total delivered - have been used by aircrew to abandon aircraft. It also manufactures fixed shock-absorbing helicopter seats designed to help the occupants survive crashes.
The company has diversified into
spacecraft reentry systems such as heatshields, parachutes and the pyrotechnics for deploying them. It designed and manufactured the parachute system
ESA's
Huygens probe which was launched on-board
Cassini in 1997 and successfully landed on Titan on
January 14 2005. This was the first planetary landing system to have been made in Western Europe. In 1998 the experience with Huygens led to the company becoming a member of the consortium which developed
Beagle 2, intended to land on Mars. However, in June
2001 the company withdrew from the project due to
irreconcilable commercial differences with the project's industrial prime contractor, who subsequently had severe problems in developing a descent system within the constraints of mass, time and cost[

December 25 2003 was unsuccessful.
