Neat, but it would have been awfully hard to see the runway when landing.

From one of the drawings hesham found, there was both an underside periscope and a backup glass pane in the floor of the cockpit.

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.

Re: Re: Various Blohm und Voss projects
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.
General characteristics
Crew: two
Length: 14.3 m (46 ft 11 in)
Wingspan: 16 m (52 ft 6 in)
Height: 3.65 m (12 ft 0 in)
Wing area: 44 m2 (470 sq ft)
Empty weight: 9,100 kg (20,062 lb)
Max takeoff weight: 13,300 kg (29,321 lb)
Fuel capacity: 2800
Powerplant: 3 × BMW 801D Propeller engines
Performance
Maximum speed: 820 km/h (510 mph; 443 kn)
Range: 2,000 km (1,243 mi; 1,080 nmi)
Combat range: 2,500 km (1,553 mi; 1,350 nmi)
Service ceiling: 11,650 m (38,222 ft)
Armament
Guns: No defensive guns provided
Bombs: 1 × SC 1000 bomb or 2 × SC 500 bombs or 4 × SC 250 bombs
These drawings are all B&V original drawings. Bottom one is interesting. Flying sausage or UFO mother ship. ;D
