RAF Herald C Mk.1 vs Andover fuselage dimensions

Pre-nationaisation. He just didn’t think enough money was on the table.

There was a high winged 748 proposed for the Indian Air Force I believe… the 758…

The Herald airframe looks alot more suitable for military conversion, no need for a knealing undercarriage etc. But of course Sir Fred wouldn’t be nationalised!

Hello Graham – I have some manuals for both 748 and Herald – will dig them out for you!

Have an original copy of the Military Herald brochure at home… will dig it out later…

Altitude boost pods? Was it proposed with extra jet engines then?

(Sorry it’s a bit off subject)

There’s a slight chine to the Herald’s lower fuselage, which suggests that they weren’t quite circular.

Quite right. My comment was based on a photo of a fuselage under construction that didn’t show the lower part. Just goes to show you cannot be too careful!

Sabrejet, I have failed to answer the stated question, unfortunately I can not give an exact answer to the question.

That dimension on my drawing is not very clear. But by using the scale on the drawing I have concluded it is either 8′ 8″ or 8′ 9″ OD. This would fit in with the 8′ 1″ given as the ID.
If you would like a copy of my poor drawings, drop me a PM.

The RAF didn’t have Heralds: but they were considered favourites for a buy which eventually was given to Avro for the Andover. There’s a recent article which deals with the procurement saga in some detail.

Thanks for the Herald diameters: I’ve been informed that the Avro 748 had an internal diameter of 8ft 1 in.

Did the RAF have HP Heralds?

This gives some cabin dimensions:

Herald brochures from the 1960s give a maximum internal diameter of 8ft 8in for an external diameter of 9ft 2in. The fuselage seems to be circular in cross section, but obviously floor and ceiling mean the floor to ceiling height is less and in fact varies depending on position from 6ft 4in to 5ft 11in.

Andover Principal dimensions

Wing span 98ft 3in
Overall length 78ft
Overall height 30ft 1in

Undercarriage Type Tricycle, retractable
Track 27ft 9in
Wheel base 23ft 9in

Sorry to go all pedantic, but the OP was looking for fuselage diameters…
