DE­SIGN

History of War - - OPERATOR’S HANDBOOK -

The Gün­ter brothers based their He 111 de­sign on the proven He 70 Blitz. As a twin-en­gine ver­sion of its pre­de­ces­sor, the He 111 was of­ten called the Dop­pel Blitz, or ‘Dou­ble Lightning’. The air­craft kept the el­lip­ti­cal wing de­sign, although the sur­faces were length­ened, and the ex­tended fuse­lage could ac­com­mo­date pas­sen­gers and later a pay­load of bombs. The orig­i­nal BMW VI en­gines were deemed un­der­pow­ered, giv­ing way to the Daim­ler and then Junkers mod­els. A sin­gle ver­ti­cal fin was some­what over­sized for the air­craft’s pro­file; how­ever, all sur­faces were de­signed for max­i­mum aero­dy­nam­ics. The de­fen­sive ma­chine guns were lo­cated in the nose and in flex­i­ble dor­sal, ven­tral and lat­eral po­si­tions.

Fac­tory work­ers labour to fin­ish a He 111 on the floor of a fa­cil­ity in Ger­many. By 1944, the He 111 was largely ob­so­lete but re­mained in ser­vice
