H.P.88 Using the H.P.80 design as it stood in early 1948, a 40% scale model was commissioned. https://i.imgur.com/ADpXVKd.png Due to lack of design capacity, the aircraft was sub-contracted to General Aircraft, which were shortly after taken over by Blackburn Aircraft. Blackburn allocated the Y.B.2...

H.P.87 As the H.P.80 was such a significant departure from previous aircraft designs, the aerodynamics of the basic design and the crescent wing itself required validation. https://i.imgur.com/VaIvpFe.png To ensure that the H.P.80 and the less advanced Avro Vulcan were able to perform as designed, ...

H.P.80 revised design Continuous work on the H.P.80 design progressed all the way until the design was frozen in September 1950. https://i.imgur.com/9YEK8sl.png The first major modification occurred in January 1948, when concerns about flutter of the fins led to the addition of a standard vertical ...

H.P.80 specification B.35/46 Once HP had shown the RAF what they wanted to build, the RAF responded by working through with HP what they actually wanted to use. https://i.imgur.com/djqkLig.png The RAF finally issued the formal specification for jet bombers in January 1947, and HP responded with a c...

You may have noticed (!) that I'm including wingplan views on a lot of these aircraft in this family. As the wing design is such a vital feature of these aircraft I thought it best to include to allow a better visualisation of the aircraft, and provide a better sense of how the designs developed.

H.P.72A "Flatfish" The second project was a radical new design, drawing on post-war information on swept wings gleaned from Arado. This design was definitively allocated a "cover" designation, and was unofficially named the "Flatfish" at HP. https://i.imgur.com/crFOkoO.png The H.P.75A was quickly d...

In June 1945 HP started design work on a replacement for the Avro Lincoln, seen as being six years into the future. Work on two alternate designs was commenced, and they were allocated HP model numbers in January 1946 H.P.75A https://i.imgur.com/iGRmzZf.png Continuing with the earlier 70 ton jet pus...

https://i.imgur.com/LzYkpOJ.png The third design was a further developed pusher, fitted with 8 Metro-Vick jet engines, and a modified wing for higher-speed flight. With the lower power available from the initial version of the F.2 engines, take-off augmentation with RATOG would be required. The 75 ...

https://i.imgur.com/c019JDJ.png Developed from the H.P.75 Manx, the second design was a tailless pusher equipped with a rider-plane. The fuselage very deep but narrow, allowing for carriage of the bomb-load stacked in two rows, 5 high. Unfortunately the original HP general arrangement diagram does ...

HP 75 ton bomber proposals In 1942 the RAF called requested designs for 75 ton and 100 ton superbombers. HP responded with 3 designs in the 75 ton class that they referred to internally as 70 ton bombers. None of these designs were given HP design numbers. After being lost from sight for many years...
