N7/46 P1040 was the swept wing version of the N7, the P1052. Two of these aircraft were built for research purposes, with thirty five degree swept back wings the first used by Hawker’s to investigate the controllability and stability of sweptback wings at low speeds and much the same engine lay out as the P1040. First flown on 19 November 1948. After some development work, one of the P1052’s was converted into the P1081. This was fully swept back on all surfaces, and the engine lay out was changed: instead of the split or bifurcated jet pipe, the engine had a straight through jet pipe, exhausting in a single pipe under the tail. A prototype first flew in November 1948.
Both the P1052 and the P1081 were used for research only, and no production was begun.
Engine: Rolls-Royce Nene, 5000 lb (2268 kg).
