Thanks for sharing.
 
Re: Re: Various Blohm und Voss projects

From one of the drawings hesham found, there was both an underside periscope and a backup glass pane in the floor of the cockpit.
 
Re: Re: Various Blohm und Voss projects

That is a (periscope) bombsight, not intended to land a plane.
 
Re: Re: Various Blohm und Voss projects

You're right. Sorry, should have looked at the drawing more closely. So it was just the glass pane the pilot used.

Thanks, that makes it a lot clearer, I don't speak German and hadn't noticed the glazing in the fuselage bottom. By the way, that looks like one heck of an armored pilot's seat.

Hi! Blohm & Voss P.170
I imagine that key word for this design is high power, light weight and low drag.(high speed aircraft)
My opinion.....
Merits...
①Cabin was used as a counter weight for heavy three engines. ⇒ short fuselage. ⇒light weight and low drag.
②Cabin was used as a vertical tail stabilizer. ⇒ delete vertical tail stabilizer. ⇒light weight and low drag.
③Wing tip engines. ⇒ reduce wing root bending moment in flight.⇒ thin wing. ⇒ light weight and low drag.
④Wing tip engines. ⇒ reduce wing tip vortex generation. ⇒ low drag.
⑤Tail cabin. ⇒ Large fuel tank capacity near C.G. ⇒ long range.
⑥Engin nacelle tail rudder. ⇒ receive high speed propeller stream. ⇒ small rudder is enough.⇒ light weight and low drag.
⑦Wide landing gear interval. ⇒ stable landing.
⑧Simple wing structure.(It's not necessary to retract landing gear into the wing.)⇒light weight and easy construction.
Demerits...
①Field of front vision is worst for this airplane, and taking off and landing is difficult.
②When one of an engine of a wing breaks down, control becomes difficult.
③Shaking in a cockpit is big and ride quality is worst. A bombing sight is difficult.
④It can't be expected that the steerability and the stability of this airplane are so excellent.
