The Ho VIII, Transport Aircraft and Flying Wind Tunnel
After three days of discussions, it became clear that our flying wing would have far better range than the others, although short of the required 4000 miles. Thus it appeared that an order for a large bomber would come our way, so we decided to build an intermediate size aircraft to gain experience.
To minimize the risk of aerodynamic surprises, we simply doubled the dimensions of the trusty Ho III. This improved the calculated L/D to 30, since the friction drag coefficient was reduced through a fivefold increase in the Re numbers.
All our calculations needed verification in a wind tunnel. As they remained unavailable, we decided to help ourselves, and put a tube shaped fuselage in the Ho VIII, to make it a flying wind tunnel.
The Argus engine used in the Ho VII would be used, with six units mounted in the wings driving pusher propellers. The wing would have a box spar, with all control rods and cables inside the spar, to free the remaining wing space for fuel tanks.
The construction progressed quickly through the spring of 1945, and the aircraft was half finished when the American forces reached Gottingen.
