Longestpants 1 Posted August 24, 2007 LFG Roland D.XVI need some pictures Wiki (bottom) "The next major design from Roland were parasol monoplane designs, the D.XVI with the Siemens-Halske Sh.III or 170hp Goebel Goe.IIIa rotary piston engines, and the otherwise similar D.XVII with the inline 185hp BMW IIIa. Both were entered into the Second Fighter Competition at Adlershof, but lost to the Fokker D.VIII." Unfortunately, could not find pictures. Share this post Link to post Share on other sites
+LloydNB 212 Posted August 24, 2007 Two versions of the D.XVI parasol fighter were completed in September-October 1918, one powered by the 160hp Goebel Goe III rotary and the other by a similarly rated Siemens-Halske Sh II rotary. The D.XVI had a fully- cantilevered fabric covered parasol wing and a slab-sided plywood covered fuselage. Armament comprised twin synchronised 7.9 mm LMG 08/15 machine guns. The D.XVI proved faster than the Siemens-Schuckert D.IV and the Fokker D.VII up to an altitude of 4,000 m but slower above that. Span 31 ft 1/2in (9.46 m) Length 19ft 4in (5.9 m) LloydNB Share this post Link to post Share on other sites

Dutch_P47M 9 Posted September 5, 2007 4-bladed prop? Pretty rare in WWI. 4-blade prop is not rare in WW1 ?? Take a good look in your WW1 airplane book. Some pilotsgraves in the Western front are even marked with an cross made from a 4 bladed prop. Share this post Link to post Share on other sites
FastCargo 412 Posted September 5, 2007 Define 'rare'. How many aircraft in WWI had 4 blade props vs total number of aircraft types? Do you have that info there Dutch? I'd like to know. FastCargo Share this post Link to post Share on other sites
+Tailspin 3 Posted September 5, 2007 Not what I'd call rare. Several very common A/C had 4 bladed props like the DH-2 and the BE 2c. Then there was the R.A.F. BE 12, FE 2, FE 8. The Airco DH 6. The Seimens-Schuckert DIII, DIV. The Handley Page 0/400 bomber. The Short Bomber. The Brits seemed to use them more than anyone else. Share this post Link to post Share on other sites
+p10ppy 2 Posted September 5, 2007 Well I wouldn’t call it rare but it certainly wasn’t the norm At least some of these (it seems to be mostly English but that could be my references) and dependant of powerplant A few of the more common seem to be totally 4 bladed (FE 2, BE 2) Breguet 14 S.E.5a BE 2a BE 2c BE 12 RE 7 FE 2 FE 8 Martinsyde G100 FE 8 F 2B DH 4 DH 6 DH 9a HP 0/100 HP 0/400 Fairey Campania Siemens-Schuckert D.IV Siemens-Schuckert D.III The interesting thing about the D.XVI is the Siemens-Halske Sh II rotary where the crank rotated in the opposite direction to the Prop beaten to the punch Share this post Link to post Share on other sites
FastCargo 412 Posted September 6, 2007 Okay, That's what I wanted to know...not 'rare', but not what I would call common either. FastCargo Share this post Link to post Share on other sites
JediMaster 451 Posted September 13, 2007 It wasn't until WWII that 4-bladed props became standard, and not the beginning of the war either. Many planes known for 4 or 5 blades late-war had only 3 early war. Share this post Link to post Share on other sites
