Description

The V/STOL blast grid at Dunsfold airfield is a steel structure built in 1960, located at the western end of the main runway. It is made of boxed steel, brick, concrete, and steel plate. The grid is rectangular, measuring approximately 10 meters by 20 meters, with the longer edge oriented east-west along the runway.

For safety reasons, the grid is currently covered with sections of steel plate, but it is believed that the below-ground structure remains intact. Based on photographs from its construction, the blast grid is set about 2 meters below the tarmac runway surface and consists of multiple steel box sections, each approximately 0.5 meters by 1 meter, supported by steel uprights around 1.5 meters tall. Inside each box section, there is a curved metal vane designed to disperse exhaust gases into the void beneath. This void is created by brick walls and a concrete floor. At the center of the grid, there is an inset lifting door made of finer box-section steel, measuring approximately 2 meters by 3 meters, which likely allows for maintenance access to the underside of the grid.

Local climate

V/STOL blast grid at Dunsfold airfield receives an average of 740 mm of rain a year. This makes it drier than 75% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 53% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 59% of listed buildings. Of these, 13 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
