Basic and Advanced Ejection Seat Trainer

Over 8000 pilots have been saved by the use of their ejection seats. While ejection is a life-saving measure, it does carry with it some risk of injury. However, proper training in the correct ejection technique can significantly reduce the risk of injury, while at the same time giving aircrew added confidence in the ejection system.

Needs

Knowing when to eject is just as important as how to eject

The ejection seat is one of the most complex systems installed in the aircraft
It is the last chance to provide the pilot for a save exit out of the aircraft in case of a severely damaged aircraft or an accident
If the pilot is not in a correct position before firing it could cause severe injury or even cause death
It produces high-G up to a maximum of about + 20 Gz
Training of the procedures, how the pilot should be positioned before pulling the handle, is essential for survival
Knowing when to eject is just as important as how to eject

Solution

In an aircraft emergency, the ability to eject can mean the difference between life and death

AMST`s revolutionary SmartEject™ control system is the heart of the ejection seat trainer. This unique and remarkable system is responsible for the complete control of the ejection sequence. For the first time, AMST`s unique SmartEject™ system allows realism and safety to be maximised with no compromise.
Using intelligent control systems technology, the SmartEject™ system precisely coordinates and controls the pneumatic firing system and the seat braking mechanisms in order to produce the required force profile of the ejection sequence (based on max G-load, loading weight and onset/offset rates) with maximum safety.
It is a procedure trainer for pilots and instructor personnel, keeps procedures realistic and efficient and provides advanced flight training. In addition, used for pilot candidate screening, advanced physiological and clinical research and for general aeromedical research applications.

Benefits

AMST’S SmartEject™ ejection seat training system gives a wide growth potential for the user training efficiency by enlarging the training realism from the basic system to the advanced system.

The design of the AMST’s ejection seat trainer is with considerable emphasis on safety, realism and reliability.
The system allows a pilot to fly a mission and then face a critical aircraft emergency. The pilot is then able to eject in a realistic way from the stricken aircraft.
The cockpit assembly looks similar to a fighter aircraft, has a pneumatically operated ejection seat with guide rails, an advanced computer control system and a comprehensive instructor operator station.
The training allows becoming familiar with the correct ejection posture and the ejection sequence, while practising their decision-making skills during simulated aircraft emergencies.

There are two possible modes in which basic ejection training can be accomplished:

In the passive ejection mode, the student undergoes an ejection initiated by the instructor. In the active ejection mode, the pilot initiates ejection via the seat-pan firing handle under the control of the instructor.
The advanced EST allows enhanced training for decision making in case of an emergency. Creates awareness on whether or not to eject and sharpens the decision-making process in case of emergency.

Features

The system is equipped with the following features

Rail Tower – High Strength Steel Mast

The mast is a very stiff steel profile and contains the guide rails for the sledge with the ejection seat. To hold the sledge with the ejection seat after firing and to lower the sledge to the start position, the mast is equipped with a failure safe lowering device. The mast has tilt adjustment. On the top is a safety damper and a distance measurement.

Ejection Seat

The seat is a generic a/c seat, mounted on the sledge with adapters. During ejection, the sledge will glide along the rails of the rail tower. The descent of the sledge/seat is failure safe. The seat is equipped with a belt retraction mechanism to fulfil the safety requirements of the simulator. Seat angle adjustment via adjustment of the mast.

Cockpit

Cockpit design is similar to a modern fighter aircraft. Moving forward/ backwards on an integrated rail system. It has basic flight instruments (angle of pitch and roll attitude, vertical speed, flight speed, vertical component of G-load, angle of attack and the parameter of the fuel gauge system, altimeter, compass, HUD and HDD and controls (stick, pedals).

Cockpit Instruments – Head Down Display – HDD

The aircraft cockpit section is equipped with software-generated instruments, displayed on TFT flat panels. The instructor can select different instrument configurations to simulate different types of aircrafts. It has an additional G-meter and an aircraft system master warning and caution system.

Instructor Operating Station – IOS

The IOS has clearly arranged sections to provide the instructor a logical and safe training run with GUI to operate the SmartEject™ control and monitoring system, a GUI to operate the flight simulator module and the recording section.

Pressurised Air System

The pneumatic ejection system consists of a compressed air cylinder, an air charging system, a pressure regulator and pneumatic valves. Controlled by a PLC according to the required G-load and trainee’s weight. Furthermore, the system is integrated in the safety system to prevent the occurrence of training emergencies.

Options

For the Advanced System

Advanced System

The advanced system includes a flight simulator, an additional IOS and a visual system. The instrument panel shows the basic flight and engine instruments. The instructor initiates malfunctions. The visual system is a three-channel back projection system.

Integrated Logistic Support – ILS

The ILS team supports the customer during the lifetime of the equipment to achieve the operational requirements, in particular operational availability greater than 95 % with affordable life cycle costs. AMST provides different levels of maintenance up to a careless package.

Building Services

AMST provides structural engineering and design of building and foundation, basic architecture design, building design, building erection supervision and infrastructure modifications.
