b17vs b24
« on: January 05, 2010, 10:04:20 PM »
ok i have read my fair share of WWII books and WWII aircraft books in most of them the b24 is said to be faster than the b17... i did the AH comparison test on the web page and this seems to not be the case, or in game. im not home but if i were i could look up more refrences but for now wkipedia will do with them stating the 24 does 290 vs the b17's 287 (i know that i shouldnt trust it but i though it was even greater not to mention different) if memory serves me right the 17 was say 300 to the 24's 315 depending on the book you read.

i have read books from 24 pilots and 17 pilots am i going nuts or am i just missing something?

I thought they used the same engines, and I think the B24 is heavier, but honestly I dont know :salute

B24: "Four Pratt & Whitney R-1830-43 or -65 fourteen cylinder radial engines at 1,200 hp"

B17: "Four 1,200 h.p. Wright R-1820-97 radial piston engines"

According to http://www.aviation-history.com/consolidated/b24.html vs. http://www.aviation-history.com/boeing/b17.html, the top speeds are as you listed, 287mph for the 17 and 290mph for the 24.

Where you see a large difference is in typical cruise speed.  This would be the speed at which you would most likely find the planes flying the tight defensive formations over enemy territory.  The B-17 is listed at 182mph.  The B-24 at 215mph.  A difference of 33mph is certainly significant.

We sometimes have to remind ourselves that the cartoon AH world of constant throttle-to-the-firewall flight is not what was experienced by the men who flew in the real deals in WWII.

wellfrom just looking at top speed on the aircraft vs aircaft page it seems that the top speeds are reversed or at least the 17's is off past 27,000ft.
i dont know everything but im out of town cant fly and boared.  :cry

When I was flying the -24 and -17 for the Collings Foundation the B-24 would do about 170-180 IAS at 30" and 2000 RPM.   The B-17 at that power setting would be doing about 160-170.

The airplanes carried the same amount of fuel, they burned fuel at the same rate but due to the higher speed of the B-24 it had a considerably longer range.

The B-24 also seems to benefit from going above 30k more than the B-17 does. The range of the B-17 drops pretty bad around 35k but I wouldnt know why (must be something technical).

The 24 had a reputation of being faster in the war and it was also more manoeuvreable but it also suffered from icing much more than the B-17 (the wing would just stop working with ice buildup). Bombers in AH fly at higher powers settings than bombers that flew during the war though.

Wiki also doesnt mention which model they are listing the top speeds for.

I just got done reading: "WOW!" by Ralph Welsh (B-24 Pilot) which was a compendium of 80+ B-24 stories, not one "Mission" recollection was at 30k or higher.   

Seeing as the known Service Ceiling was 28k, I doubt it was "regularly" exceeded.   In fact I'd say the common alt of 24's in WWII was 25-27k.

I read somewhere the B24 wing is "laminar flow". The same technology that gave the P51 it's incredible range and speed. If true, I'm sure that has a part to play too.

From what I've read and heard from talking to a pilot who flew both B-24's and B-17's in the war, the B-24 was faster, carried more, and had a longer range.  The B-17 was easier to handle (lower control forces) and might have been able to take more damage.

In the war, there were more B-24's than B-17's built (about 18,000 and 13,000 respectively).
