DESDEMONA

The Revolution in Simulation

The investment in the most modern flight training equipment is one of the most important decisions you can make to protect aircrew and aircraft. DESDEMONA is the world’s only civil & military versatile, sustained G motion platform with six degrees of freedom and with unlimited performance in yaw, pitch and roll. Powerful mission simulation and advanced flight training.

Needs

Extended simulation in the civil and military aviation becomes a more and more important role.

Modern agile fighter aircraft and attack helicopters operate in an extremely dynamic motion environment.

Pilots of such agile aircraft face the ever-present risks associated with spatial disorientation and motion sickness. To minimise these problems, adequate training is essential.
To familiarise the modern pilot, with the sometimes-drastic effects of spatial disorientation phenomena and illusions frequently experienced in today’s highly sophisticated flight operations.
Therefore, a training device must be an equally agile and dynamic motion simulator.
AMST’s DESDEMONA is a truly unique simulation tool, due to the special characteristics of its remarkable and innovative motion platform.
No other simulation device currently exists that can do what DESDEMONA can.

Solution

DESDEMONA’s range of potential simulation and its inherent versatility makes it a truly revolutionary device. It is a complete solution to the requirement of producing a total motion environment for military-, civil-, research- and training applications.

DESDEMONA is a single source solution for commercial and military simulation.
Dependant on the model DESDEMONA can operate up to ± 3 G or with the DESDEMONA NG up to -3 G to +7 G.
Because of its significant diverse motion platform capability, DESDEMONA can be used to simulate a wide range of land, sea, space and air platforms.
Because of the design with a six DOF unique motion system producing sustained G, currently DESDEMONA is used for research programmes, for training of inverted and deep stall manoeuvres for the Royal Netherland Air Force, for brownout training for Chinook helicopters and for stall recovery training for transport aircraft.

DESDEMONA can be used for a variety of roles including:

Dynamic and Tactical Flight Simulation for fixed wing, rotary wing and fast-jet aircraft
Extended flight envelope training
Civil aviation Upset Recovery and Loss of Control in Flight (LOC-I) training
Spatial Disorientation training
Advanced physiological, clinical and aeromedical research applications
Research and development platform
Equipment testing

Benefits

DESDEMONA pushes the limits of motion simulation to the next level not seen anywhere else in the world currently.

It is a motion simulator, disorientation trainer and advanced research lab, all in one. Simulation of complex situations that may occur during flight or any other motion simulation is almost limitless.
The main benefit of the DESEDEMONA is the ever-increasing need to familiarise the modern pilot, with the sometimes-drastic effects of spatial disorientation phenomena and illusions frequently experienced in today’s highly sophisticated flight operations.
It is a high fidelity motion platform with sustained G-load capability and unlimited attitude controllability
Easy adaptability for individual customer needs, due to the modular design philosophy in H/W and S/W with full data transmission, recording and debriefing capabilities.
Rapid scientific-based training development for individual customer needs with networking capabilities to other simulation environment and cockpit exchangeability
Efficient and superior device for the demonstration of disorientation phenomena and illusions and for pilot candidate screening
Provides a wide range of flight procedures such as unusual attitude recovery, spins and stall manoeuvres, super-agile manoeuvres, aircraft carrier operations, ground-based vehicle training and for motion sickness desensitisation
Improvement of upset recovery simulation including sustained G-forces by implementation of an extended flight model for symmetrical and asymmetrical stall scenarios with wing drop and reproduction of sustained G-load
Evaluation was made by BOEING and AIRBUS test pilots: “Aerodynamic model is very representative for real aircraft, new centrifuge cueing provides excellent key motion cues, especially loading and unloading, experience of sustained G-load has high training value and achieves perfect balance and a positive attitude for flight safety”

Features

The original is always better than the copy

Main Rotation System

Main drive system consists of eight electrical AC motors acting on a central shaft connected to the main arm. This modular system ensures that in case of a failure in one of the motors, operation continue with less performance, whilst the defective motor quick released from the shaft. The main arm optimised in weight and has a high stiffness.

Linear Drive

The linear drive system is a proven system coming from the chairlift technology and consists of 5 AC motors acting on a central wheel. The ropes connected to a sledge that can travel along the arm for a distance of total eight meters and carries the heave system.

Heave System

Electro pneumatic cylinders drive the heave system. It can move the gondola system for a distance of two meters.

Gondola System

The gondola system consists of a roll system, the pitch system and the inner yaw system with the cabin. The roll system, the pitch and the inner yaw system have maintenance free torque motors and can rotate continuously. To ensure the unlimited rotation each system is equipped with slip rings and rotary joints.

Cabin

The cabin contains of a functional aircraft cockpit mock-up including visual hardware, flight controls and instrumentation, an adjustable pilot seat, as well as audio/video/intercom equipment, sound system and computer hardware. The visual system (OTW) represents a Field of View of minimum 120° by 50°.

Control Room Facilities

Engineering/operator station with sophisticated, easy-to-use Graphic User Interface (GUI) and hardware features for operation and control, monitoring and technical diagnostics. The profile editor for pre-programmed training profiles and envelope settings in closed-loop mode, safety and emergency stop functions, video and intercom systems.

DESDEMONA – The Netherlands 2006

After years of development DESDEMONA was installed in a new building located within the TNO compound. The original idea for this development was based on a combination of existing simulators at TNO for their space programme. It is in operation since 2008 and now operated by DESDEMONA BV.
