Napier-Railton parachute test vehicle

In 1951 the Napier-Railton was purchased by the GQ Parachute Company of Woking to test aircraft parachutes at Dunsfold airfield. GQ had the car modified with the addition of specially made disk brakes and fitted with test equipment capable of deploying an aircraft braking parachute at high speed, and then retracting the parachute when the speed had dropped to about 30 knots. The car was normally driven by Sir Geoffrey Quilter but also other members of the company. When the testing work had been completed, the car was sold on to be raced in VSCC meetings.

Top Gear

The real history of the Top Gear Track

  • 1938

The BBC Top Gear track has been laid out on the main runway of the former WWII RAF and RCAF air base.   The perimeter roads used for Gambon and the finish line were laid over the route of original B-Roads that were ripped up when the airfield was constructed in 1941.  One cottage, Broadmead, was situated where the TopGear FollowThrough is now, but the cottage was lifted whole and winched half a mile on rollers to the otherside of the airfield.

VTO grids – Listed Grade II

The main runway has the unique Vertical Take Off Grids, known as VTO Grids or Hover Grids – used for the tethering of jump jets such as the Harrier whilst hovering. These are located on aprons that adjacent the main runway and are within the Operational Readiness Platform [ORP].  Beneath these gratings is a large void chamber to take the hot air, condensation and gases from the downdraft of the jet engines of the aircraft. Within the eastern Engine Testing Pen there is a similar arrangement that is a unique feature to Dunsfold.

Bomb Stores Site

Dunsfold Bomb Stores Plan

The Bomb Stores Site has two access roads with seven concrete hard standings in between and earth banks separating each hard standings or bays. These bays were used to store the bombs which were placed on wooden frames. The earth banks that separated each bay gave a degree of isolation should there be an accident and these are still visible.

Runways

It is a rare feature that all three runways survive at their original lengths and are connected with a complete perimeter track with at least 75% of the aircraft hardstanding.
Two runways are much rarer than others elsewhere in the UK as they have a large number of the Mk II airfield lighting fittings intact, together with the cast-iron drains and French drains along each side of the runways.

Runway immediately after construction 1942

Around 1942 but note and contrast the  parallel “runway feature” alongside the main runway.

The runways were constructed for a Class ‘A’ bomber airfield. The white concrete of the runways and perimeter track were sprayed with a mixture of tar and wood chippings. This dark textured finish was optically non-reflective and from the air closely resembled grass. The chippings also added extra surface grip without damaging the aircraft tyres.
