Simulators for ground vehicles are becoming a significant
part of the simulation industry. However, the technology
employed employed has fallen into the following categories,
* high-end research simulators for vehicle manufacturers
and Government Departments, carrying a very high price
* flight simulator-based designs, with aircraft cockpits
replaced by ground vehicle cabs, which are neither
optimal on performance nor cost-effective
* very low cost simulators with off-motion displays and
limited motion range, limiting the scope of application.
Simularly, commercial flight simulation technologies fall
into the following:
* high fidelity FAA/JAR level C & D devices with full 6 DOF
motion and large collimated displays
* flight training devices that provide similar levels of
cockpit reproduction as level C/D but with no motion or
* CBT training devices.
It is becoming apparent that new trends are emerging in the
traditional flight simulation market place. In particular
there are moves to harness the improving level of PC-based
performances to substantially reduce costs and consequently
re-evaluate the training potential of simpler devices. The
project aims to encourage system integrators and simulator
manufacturers to offer level A and B training capabilities
at a price below that currently being asked for FTD
devices. The customer would then be able to select a well
specified standard system and concentrate on the Cabin,
Host Computer, Image Generator, Vehicle Models and other
simulator specific aspects, whilst knowing exactly what
the combined motion and visual performance would be. By
the introduction of such standardisation, design "time
costs" and time-to-market for the customer would all be
The strategy of the project would be split into three
1) Common Research Phase
The Simulator platform will comprise the following:
* an electric motion system
* an integrated image display system.
These components are closely linked and interacting. An
underlying objective is to integrate these to provide a
standardised interface and performance "shopping list" that
system integrators could use to predict total system
Many studies have been and are being undertaken by various
military and civil institutions worldwide into the human
factor requirements for appropriate fidelity in simulation.
However, the primary specification will come from the
existing JAR requirements for level A/B systems. Additional
sources of information will include simulator integrators
and end-users, where possible.
2) Industrial Development Phase
This phase would include design, development and building
of the prototype ready for integration.
3) Integration and Validation phase
A test platform will be set up in order to produce an
experimental evidence of the validity of the above-defined
solutions, which could form the future reference to be used
by customers in the field of ground transport in order to
fix their priorities and select their options. Involvement
of an Associate Integrator is the key to this phase.
2.1 Projection Display System
Projection display systems for ground transport simulators
will be examined in order to:
* determine the exact display system requirements for the
different training requirements
* utilise existing technology to meet the identified
training requirements/cost restraints, where possible.
* conduct research/development to provide new technologies
to meet other requirements identified at appropriate
* build a product matrix to cover as many applications as
* achieve integration with motion.
2.2 Motion System
The cab motion system will be developed in combination with
the visual display system in such a way that the following
requirements are met:
* low cost
* acceleration and travel capacities suited to the
movements to be simulated
* modularity of adjustment software
* electromechanical jack technology
* integration of display
* accommodation of a wide range of cab/cockpit types.
