“ ….. The (Vickers-Supermarine) design team would do better by devoting their time not to the official experimental fighter (i.e.F.7/30) but to a real killer fighter……my opposite number in Rolls-Royce…A.F Sidgreaves and I decided that our two companies should … finance … such an aircraft ……

…. that in no circumstances would any technical member of the Air Ministry be consulted or allowed to interfere with the designer”

Sir Robert McLean – Chairman Vickers Aviation Ltd.

Sir Robert McLean

Ernest Hives

R.J. Mitchell

Supermarine Type 300

slide23

Beverley Shenstone

Canadian aerodynamicist

Joined Vickers-Supermarine in 1932

Used Ludwig Prandtl’s theories of elliptic wing planforms in the Spitfire design

Spitfire wings (NACA 2200 series) were VERY thin by comparison with conventional wisdom - 13% root T/C tapering to 6% T/C at tip

Alan Clifton

Structures

slide27

Joseph Smith

(1897- 1956)

Succeeded RJ as Chief Designer

Maintained the same basic shape to the Spitfire while doubling the weight and power output from the engine.

Took Supermarine technical community right through to the jet age

250 sub contractors were involved in the Spitfire by 1942. By end of 1944, Supermarine had 63 units, staffed by almost 10,000, half of them women, compared to 2500 at the beginning of the war.

slide43

What made the Spitfire design so good?

  • Basic semi-elliptic wing planform
  • Low wing loading - 21-25 lb/sq. in.
  • Knife edge elliptic wing tips
  • Wing twist +2 deg to – 0.5 deg
  • Thin wing
  • Gentle pressure gradients – more stable boundary layer
  • Wing/body fairing
  • Small tail unit
  • “Meredith” effect on lower wing surface components
  • Minimal frontal area cowling
  • Ultra slim fuselage
