The (g)Force is with us!

In what is quite a milestone for the development of our Spitfire Mk.IX, we have published the plans for our G-Force seat.

The Heritage Flight Simulation G-Force Seat

The effect achieved with the pneumatic bladders and belt tensioner is subtle but adds tremendously to the overall immersion. It provides a cost-effective means of incorporating G-Force simulation into the HFS offering by way of pneumatic cushions and seatbelt pressure on the pilot. The Pneumatics Driver design builds upon that of XXPELLE, who’s build he shared on the xsimulator.net community site. I am grateful to him and to the various community members who pitched in with comments and assistance when needed. As such I have also made my upgraded Pneumatics Driver design available on that site and here for use by the community.

Heritage Flight Simulation G-Force Seat Design

We elected to use a G-Force seat rather than motion simulation due to a number of factors:

  1. A motion platform is unable to provide sustained g-force simulation, for instance when an aircraft is pulling constant g’s in a loop or steep turn. Instead it will provide an initial heave and then wash out gently when the actuator limits have been reached. This is not very convincing especially in combat aircraft.
  2. In VR any discrepancy between perceived and real motion leads very rapidly to onset of motion sickness. Hence a motion platform is less than ideal with VR.
  3. The cost of our G-Force seat is a fraction of the cost of a full motion simulator.
