http://www.csd.uwo.ca/~pettypi/elevon/baugher_other/ju87.html Believe it or not, the father of Ju 87: Junkers K 47 Type:Junkers K 47 is a two-seat fighter. Enginene 420-hp (313-kW) Siemens-built Bristol Jupiter VI radial piston engine. Performance:maximum speed 180 mph (290 km/h) at 9,845 ft (3,000 m); climb 9,845 ft (3,000 m) in 6 minutes 18 seconds; service ceiling 26,575 ft (8,100 m); range 419 miles (675 km). Weights:empty 2,535 lb (1,150 kg); maximum take-off 3,604 lb (1,635 kg). Armament:two fixed and one trainable 0.312-in (7.92-mm) machine guns. http://www.angelfire.com/yt2/glennsaircraft/junkerk53andk47.html
That is an interesting picture but I have some serious reservations about the service ceiling 26,575 ft part of it. This is the same ceiling tht most passenger jets fly and I don't think that clunker or junker would get even close.
Ta152, must admit it sounds incredible now that you mention it. I tried to check on other sites on this but it seems to go even higher...: http://www.luftfahrtmuseum.com/htmi/itf/juk47.htm Service ceiling : 10000 m Some others in competition with Ju 87: http://www.csd.uwo.ca/~pettypi/elevon/baugher_other/ju87.html Ar 81 V3 Ceiling: 7700m Ha 137 V4 Ceiling: 7000m
Might not be a silly as it sounds... Lancasters operated at 20,000ft with max bomb load and the Spitfire Mk IX had a service ceiling of 43,000 ft but I bet the controls were a little vague at that height.... [ 28. July 2003, 07:58 AM: Message edited by: Martin Bull ]
For the Lancaster and Spitfire they had the fuel injection and supercharged Merlin engine. This bird that claims 26,000 on a Bristol Jupiter VI engine that has no supercharger or fuel injection is suspect. There is nothing for the crew or engine to breath at 26,000 feet. I know the crew can take Oxegen tanks if they don't freeze to death first in the open cockpit but that engine without help from a turbocharger or supercharger will not work at that level. I think the German military padded the numbers a bit and no one had bothered to check the real numbers. Why would a dive bomber need to go to 26,000 feet in the first place ? If they started their dive at that level they would be a wingless missle by the time they got to 1,000 feet. I would guess a plane like that would get to 15,000 feet and run out of steam. I could be wrong but I don't think so. That last plane that KP posted looks more like the father of the Stuka that the first one does.
That's a good point, Ta - I hadn't considered the supercharging aspect. You may well be right about the 'exagerrated claims', Germany at that time successfully created many myths about the Luftwaffe. Such as the 'record-breaking' Bf109 which, I believe (?), bore little resemblance to a production 109....
And remember the K47 was built in 1929!! No way it could fly to 26,000+ feet. A redial engine would give out long before then. It was designed for dive bombing, yes, but not with anything like the speed or altitude of it's offspring The Ju87 was originally powered by a Rolls Royce 'Kestrel' when it flew for the first time in 1935. This was changed to a Jumo 210Ca 640hp unit for the and a 210Da 680hp unit for the A2. Later, a Jumo 211A direct injection unit (1,200hp) in the Ju87B variant. I haven't yet found a site that gives climb rates or service ceilings for the Ju87's but I'll keep looking. The Ha137 was built by Blom und Voss around 1935. There were six variants built but none ever flew any more than test flights [ 28. July 2003, 05:16 PM: Message edited by: KmPok ]
