Handley Page HP.103,a Jet Provost conversion Project

[hesham]

Hi,


the Handley Page HP.103 was a conversion of Jet Provost,into a laminar flow control
studies during the 1955,it was powered by one Armstrong Siddeley Viper A.S.V.5
engine.

RAE Aerodynamics explored laminar flow for many years. HP employed Gustav Lachmann (co-patent holder, HP "slots") before, during and after WW2, 1960s as Head of Research. The settled notion was of sucking the boundary layer, small turbine somewhere on board, electric-razor-style perforations in the leading edge. 1950s/60s MoS/MoA had a modest Aircraft Research budget to fund those RAE ideas seen in the Ministry as of practical potential. (see: SC1, FD2, Hunting Jet Flap...) Marshall MA.4+David Budworth turbine, Cranfield Lancaster, then Lincoln carrying an HP airfoil mid-upper. Lachmann put up various flying test bed notions, inc. this JP, and a DH.125.

The issue with sucking was gunge (flies in the pores) and maintenance. That and the invention of the big fan, permitting cheap long haul, dished the notion.
