First Martin-Baker deliveries for JSF Partner Nations

http://www.martin-baker.co.uk/news---ev ... eases.aspx

"Martin-Baker has completed the first production configuration US16E Ejection Seat for their F-35 Lightning II Joint Strike Fighter (JSF) aircraft for the partner nations. The US16E is the only ejection Seat in the world that has demonstrated compliance to the entire range of accommodation, physiological and ejection performance requirements for the JSF programme.

The Royal Air Force (RAF) is the first JSF partner nation scheduled to receive a production configuration Lockheed Martin (LM) F-35 Lightning II aircraft; the first UK aircraft is known as BK-1.

To mark this occasion, Wg Cdr Willy Hackett RAF and Lt Cdr Uves Wood RN from the Joint Combat Aircraft (JCA) Integrated Product Team (IPT) at Abbeywood, visited Denham on the 24th May 2011. They are pictured below with James Martin, Joint Managing Director of Martin-Baker.

Wg Cdr Hackett explained “Next year RAF and RN pilots will begin flying our first 2 JSF aircraft at Eglin Air Force Base in the US in a pooled arrangement with the USMC, as part of the preparations to build a UK Test and Evaluation Squadron, which will allow UK participation in JSF Operational Test at Edwards Air Force Base. This will be key to ensuring the UK fully understands how this 5th Generation aircraft performs and operates so that we can eventually use F-35 at a time and place of our choosing. For a pilot flying a complex combat aircraft their Ejection Seat is, in the end, critical to their ability to safely exit a stricken aircraft and return home to their families. Martin-Baker, with decades of experience and a proven track record of saving over 7350 lives has been chosen on a best value basis, as the sole supplier of ejection seats for the JSF programme, ensuring that our pilots can fly with confidence knowing that in extremis they are in safe hands.”

The Royal Netherlands Air Force (RNLAF) is the second JSF partner nation scheduled to receive the production configuration F-35 Lightning II aircraft; the first RNLAF aircraft is known as AN-1 and will also be operated at Eglin AFB. To mark the completion of the AN-1 Ejection Seat, Lt Col Jan Van Tilburg, the Military Air & Deputy Defence Attaché for the Netherlands visited Denham on 8th June 2011 and was joined by Jon Rambeau, LM VP International Programs and Peter Livingstone Managing Director of LM UK.

With the completion of BK-1 and AN-1 Seat deliveries, Martin-Baker will have completed the manufacture of all Low Rate of Initial Production (LRIP) Lot III Seat deliveries for delivery into LM Fort Worth."

Successful tests on F-35 Joint Strike Fighter Aircraft confirm Airborne Systems expertise in ejection seat parachute systems 06 July 2011

http://www.qimtek.co.uk/news/successful ... -2408.html

"Llangeinor, South Wales, UK - Airborne Systems, Llangeinor, Bridgend, a world leader in the design, development and manufacture of military parachute and aerial delivery systems, continues to demonstrate its expertise in the development of exceptional ejection seat parachute systems, with the recent completion of the final tests for the US16E Ejection Seat system of the F-35 Lightning II Joint Strike Fighter (JSF) combat aircraft.

The Martin Baker US16E Ejection Seat contains several parachutes designed by Airborne Systems Europe at Llangeinor which have been certified for flight release after a series of rigorous parachute and ejection tests conducted by Martin-Baker. Martin-Baker has worked with Airborne Systems companies for more than 60 years from the advent of the first autonomous ejection system developed in 1951.

The escape system ensures aircrew can eject safely in an emergency situation however extreme and will be fitted to all 3000-plus F-35 aircraft which will be flown by armed forces across the globe.

Dr. Adrian Jones, Airborne Systems Europe Technical Director, explained: ”The ejection seat is initially stabilised after ejection by a reefed conical ribbon drogue parachute. The inflation characteristics of this drogue parachute allow the reduction of the effect of the deceleration on the seat and pilot. After separation from the seat, the pilot is saved by Airborne Systems Aeroconical® Type 6000 main parachute. The Aeroconical® parachutes are the most technically advanced parachute in the world as they enable safe recovery in the most extreme conditions.

Jones continued: “The Type 6000 main parachute is packed into a parachute container which is ballistically deployed from the seat. The parachute container is also equipped with an Airborne Systems auxiliary parachute which controls its flight trajectory in order to prevent potentially the striking of the pilot or its main parachute by the container itself.”

The US16E Ejection Seat is qualified from 0 knots at 0 altitude (stationary aircraft on ground) to 600 knots at 50 000ft (15 240m), with the widest possible pilot nude weight range (103lbs to 245lbs – 46kgs to 111kgs).

The system has been tested to its limits from a full scale front section of the aircraft, complete with ejection seat and mannequin at launch speeds in excess of 600 mph down the Martin-Baker test track. More than 30 ejection seat tests have been completed with the production configuration in the UK, France and in the US.

Chris Rowe, Managing Director for Airborne Systems commented: “Airborne Systems ejection seats parachutes systems are already fitment to all Martin Baker ejection seat as used in fighter aircraft such as the Typhoon, Euro Fighter and we are delighted that our engineering expertise here in Llangeinor is once more being recognised and will continue to save pilots’ lives in all emergency situations and around the world.”

New JSF ejection seat designed for a perfect fit By: Andrew Healey Farnborough Air Show >> July 2006

http://www.ainonline.com/airshow-conven ... Bmode%5D=1

"It’s not only movie theater seats that are now designed with the fuller figure in mind. Martin-Baker (Hall 4 Stand D4) says its system development and demonstration (SDD) ejection seat, most recently selected by Lockheed Martin for its F-35 Joint Strike Fighter, contains features designed to accommodate larger aircrew.

The UK firm’s marketing manager, Richard Staines, said the SDD seat, known within the JSF community as the US16E, “provides an unprecedented balance of performance parameters, such as safe terrain clearance and physiological loading limits, pilot boarding mass and anthropomorphic accommodation ranges.”

The seat weighs less than 180 pounds and provides 30g of crash protection. Yet it is designed to fit a broader range of aircrew statures, ranging from smaller women to larger men–all in full flight gear. A seat-tilt capability of nearly six degrees about an attachment point on the cockpit floor ensures that it meets the full range of these physique criteria.

Actuator encoder feedback to the aircraft databus is provided to allow automatic adjustment, helmet-mounted display information and zone restriction. This ensures that pilots cannot put themselves in a potentially unsafe position by transgressing, for example, the forward ejection clearance line or their proximity to the canopy.

An auto-eject system has been introduced to counter the lift-fan failure condition for the F-35B STOVL (short takeoff vertical landing) aircraft.

SSD is a development of the Mk16 product line that has been successfully integrated in the Raytheon Texan II (JPATS), Eurofighter Typhoon, the NASA T-38N upgrade program and other aircraft platforms. “From an ejection standpoint, SDD has introduced challenging requirements from cost and technical performance perspectives,” explained Staines. “Some nine years away from full-rate production, the production seat price has already been fixed. The seat, like all other aircraft components, feeds into the aircraft cost model and will be meticulously tracked.” [Nothing relevant after this.]

Synopsis of Lecture to RAeS Loughborough Branch on 08 Mar 2011
Martin-Baker: the JSF story so far by Steve Roberts, JSG IPT Lead, Martin-Baker
Aircraft Company Ltd


http://homepage.ntlworld.com/john.oller ... 20seat.pdf

"...The seat incorporates a parachute and drogue located behind the pilot’s head. It also incorporates a life support system, an integrated harness together with arm and leg restraints. It has five separate operating modes which are a function of aircraft height and speed. The rate of descent is lower than for any previous ejection seat being less than 7 m/s even for the largest male pilot.

The US Navy required the ejection seat to be modular in construction such that it could be removed from/fitted to an aircraft on a sub-assembly basis. This necessitated a re-design of the parachute container to allow the seat harness to be removed without the need to unpack the parachute.

Martin-Baker ran a US/UK competition for the supply of the Personnel Location Beacon. The competition was won by H R Smith in the UK. The Beacon provides a signal which can be picked up by low earth orbiting satellites. This in turn allows a pilot who has ditched into the sea to be located anywhere in the world within two minutes.

http://www.hr-smith.com/hr-smith-news/i ... tor-beacon

The pilot’s helmet incorporates a Virtual Head-Up Display which provides him with an image of the scene around the aircraft. This image is derived from a variety of day camera and infra-red cameras located on the aircraft fusalage. It was essential for the Display to be plugged into the aircraft avionics data bus and for the plug to be extremely reliable. The ejection seat incorporates a plug which meets all the reliability criteria and is suitable for data rates up to 1.6 GBaud.

Neck protection is provided by means of a “Catcher’s Mitt” inflatable device which supports both sides of the pilot’s helmet and also provides support to the top and /back of the helmet. This device is also held in a container located behind the pilot’s head. The device is vented before the parachute is deployed. The device has been tested and proved to inflate under simulated 50,000 ft altitude conditions.

The F-35-B (STOVL) aircraft has additional failure modes associated with Lift Fan, Vane Box, Lift Fan Drive Shaft, Roll Duct and Turbine failures. A typical pilot takes two seconds to react to the ejection klaxon or one second if warned in advance of a likely failure. In the case of a STOVL related failure, ejection must take place within 0.6 seconds. Hence it was necessary to install smart failure sensors on the aircraft to automatically fire the ejection circuit mounted in the back of the seat....

New Small Personal Locator Beacon 27 September 2010

http://www.hr-smith.com/hr-smith-news/i ... tor-beacon

"UK based Techtest has developed yet another variant in its long established line of 406MHz Personal Locator Beacons. This series of products makes full use of the Cospas Sarsat search and rescue satellite system to minimise the detection and location time in an emergency.

Techtest pioneered the early integration of a GPS (Global Positioning System) receiver into portable emergency beacons to provide levels of position accuracy previously only associated with installed aviation emergency transmitters. In particular, the Series 500-27 personal locator beacon with GPS has demonstrated its effectiveness not only in real emergencies, but also during many trials which include tests under extreme climatic conditions in Antarctica during RAF Expedition Southern Reach, and live ejection seat testing by Martin-Baker for the F-35 Joint Strike Fighter program.

The 500-32 Series of PLB's offers similar features but in a more compact case. Smaller in all dimensions with a 35% reduction in volume over the 500-27-07 PLB whilst providing the same performance. The use of state-of-the-art battery technology and optimised electronics has enabled Techtest to produce a truly revolutionary package, providing a small beacon that can still operate for 48 hours at -20°C."

Looking at the July 2011 gif the parachute container of future F-35 will be more like a pyramid shape. Thanks!

The ejector seat goes through the canopy instead of having the canopy blown off first?

http://www.newscientist.com/blogs/onepe ... 35s-e.html

"...an "emergency transparency removal and structural severance system" made by Pacific Scientific Energetic Materials, which uses a small, controlled explosive to fracture and remove the canopy clear of the soon-to-be-ejecting pilot...."
&
Emergency Egress Systems

http://www.mcselph.com/eesys.htm

"Saving lives with controlled explosive is paramount at PSEMC. Our Emergency Transparency Removal and Structural Severance Systems can be installed as original equipment or as a retrofit with weight, cost and performance advantages. PSEMC has over 35 years experience in emergency pilot egress from fixed wing and rotary aircraft. Canopy Fracturing/Severance Systems instantaneously remove the canopy transparency and opens a clear path allowing immediate safe aircrew egress. Structural Severance Systems using flexible linear shaped charge severs the aircraft structure and allows separation of a aircrew module for safe escape form a disabled aircraft. Egress systems include aircraft platforms such as the, F-111, B-1B, Space Shuttle/747 Carrier, C-17, AH-1, AH-64, JAS-39, T-6, F-35, T-38 and many others."

I just remember reading something recently that modern canopies were too sturdy to eject through.
