"The Meredith duct is a ramjet powered by the heat wasted in cooling."

In an attempt to boost the performance of the Spitfire Mk1 in May 1940, RAe scientists (including Hayne Constant) developed a 'propulsive duct'. This was in essence a simple ram jet, fed by petrol, utilising the Meredith effect. It was housed in a 48-by-30-by-15-inch (122 cm × 76 cm × 38 cm) deep duct mounted on the fuselage centre line and resembled a third radiator. Bench tests showed that the increase in speed was not significant and the device was not flight tested. In 1943 the idea was reconsidered as a counter to the threat of the V1. Aircraft such as the Hawker Tempest and Gloster Meteor were not widely available and the Spitfire would only be able to intercept in a diving attack. A. D. Baxter and C. W. R. Smith at Farnborough reviewed the 1940 work and concluded that it was practical but problems with drag and pressure loss were encountered and the V1 had been beaten before they were solved.
