b24 vs b17 range and payload

Only 218 C-109s were actually converted. Armed with no less than 13 0.50-calibre machine guns, including two in a new chin turret for defense against head-on attack, the B-17G fairly bristled with machine guns. A payload range diagram (also known as the elbow chart) illustrates the trade-off between payload and range. Turbo-supercharged radial engines (a uniquely American development) were to give the necessary high-altitude performance, and heavy defensive armament was to provide protection against attacking fighters. Accuracy was to be achieved with the Norden bombsight, developed and fielded in great secrecy during the 1930s. Long-range anti-submarine Liberators played an instrumental role in closing the Mid-Atlantic gap in the Battle of the Atlantic. The B-17 was designed by the Boeing Aircraft Company in response to a 1934 Army Air Corps specification that called for a four-engined bomber at a time when two engines were the norm. The B-24D initially featured upper, belly and tail turrets, plus swiveling single guns in the waist and on either side of the nose. Flying mainly from bases in the Northern Territory, Queensland and Western Australia, aircraft conducted bombing raids against Japanese positions, ships and strategic targets in New Guinea, Borneo and the Netherlands East Indies. With the American entry into World War II, production of the B-24 increased. The tailplane featured two large oval vertical stabilizers mounted at the ends of a rectangular horizontal stabilizer. Munson, Kenneth, "Bombers 1939-45, Patrol and Transport Aircraft", Macmillan Publishing Company, Inc., New York, Blandford Press Ltd., 1969, LCCN 77-92035, page 156. [citation needed].

The aircraft demonstrated unstable flight characteristics with all storage tanks filled, and proved very difficult to land fully loaded at airfields above 6,000ft (1,800m) MSL in elevation, such as those around Chengdu. The C-109 was a dedicated fuel transport version of the B-24 conceived as a support aircraft for Boeing B-29 Superfortress operations in central China. Leutnant Heinz Knoke (who finished the war with 31 kills) shot down the Liberator. Crashed B-24s were the source of the landing gear units for the strictly experimental Junkers Ju 287 V1 first prototype jet bomber airframe in 1945. The conversion had a hinged cargo door at the nose eliminating transparent nose and large cargo doors installed in the waist area. Mosquito Vs B17 #13342705. The waist gun hatches were provided with doors. Early model Liberators were fitted with a top-mounted turret, a tail turret and single machine guns located in the waist and in the glazed nose. In his autobiography, Fate is the Hunter, the writer Ernest K. Gann reported that, while flying air cargo in India, he barely avoided crashing an improperly loaded C-87 into the Taj Mahal. Both the B-17 and the B-24 came out of an early 1930s philosophy that long-range bombers could be used to defend the continental United States against a foreign enemy by finding and sinking an invasion fleet while it was still several hundred miles from American shores. [40], Two squadrons of the South African Air Force (SAAF) also flew B-24s: 31 and 34 Squadrons under No 2 Wing SAAF based at Foggia, Italy. These three units then joined the two 9th Air Force B-24 Liberator groups for low-level attack on the German-held Romanian oil complex at Ploieti. The basic element of a typical formation was a squadron box of 9 or 12 aircraft; three squadron boxes staggered vertically and horizontally formed a group, and three groups in trail formed a combat wing. pp. Plans originally called for 2,000 C-109s to support 10 groups of B-29s (approximately 400) in China, but the capture of the Mariana Islands provided a far more easily resupplied location for raids on mainland Japan, and the plans were greatly scaled back. The radio/radar operator sat behind the pilots, facing sideways and sometimes doubled as a waist gunner. The Liberator peak overseas deployment was 45.5 bomb groups in June 1944. One of these was captured at Venegono, Italy on 29 March 1944. Eighty minutes into their flight, German fighters swooped in, taking their toll on the B-24 squadrons. The defensive armament of the B-24 varied from transport variants, which were usually unarmed, to bombers armed with up to ten .50 caliber (12.7mm) M2 Browning machine guns located in turrets and waist gun positions. 29th Apr 2007, 21:34. Some were fitted with a belly pack containing fixed, forward-facing cannon. Arrangements for signal lighting varied from group to group, but generally consisted of white flashing lamps on both sides of the fuselage arranged to form the identification letter of the group. Within weeks, the First Provisional Bombardment Group formed from the remnants of the Halverson and China detachments. Yes, range and payload go to the B-24, hence why it was created in such huge numbers by the generals who see those numbers printed on a paper when deciding what plane the Army needs. OPTIONAL: Maximum internal bombload of 7,983 kg (17,600 lb). The PLAAF had two B-24Ms captured from the Chinese Nationalists during the Chinese Civil War and operated until 1952. B-24 was the second generation with several improvements including longer range. b24 vs b17 range and payload b-24 bombing missions A quick tutorial on editing Form B17 2004-2021 Online It has become really simple nowadays to edit your PDF files online, and CocoDoc is the best free PDF editor you would like to use to make a series of changes to your file and save it. Wind tunnel testing and experimental programs using an existing Consolidated Model 31 provided extensive data on the flight characteristics of the Davis airfoil. Knoke reported: "The fire spread out along the right wing. Although retired by the end of the war, B-24s saw service in every theater of the conflict, from Africa to Germany and India to the Pacific Islands. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. This wing was highly efficient allowing a relatively high airspeed and long range. On this Wikipedia the language links are at the top of the page across from the article title. This was a major component of the USSTAF and took a major role in strategic bombing. Books repeated highlight the fact that the Mosquito bomb load over long distance was equal to a B17 (approx 4,000lbs). In a joint venture between the Army Air Forces and the Office of Strategic Services (OSS) code-named Operation Carpetbagger, pilots and crews flew specially modified B-24Ds painted with a glossy black anti-searchlight paint to supply friendly underground forces throughout German-occupied Europe. This was the B-24's most costly mission. The C-87 flew in many theaters of war, including much hazardous duty in flights from Labrador to Greenland and Iceland in the North Atlantic. Designed to help the U.S. and allies leverage emerging technologies to create a resilient multi-domain network. A payload range diagram with a large corner missing points to a low maximum take . Failing to do this meant that the B-24 flew slightly nose high, and it used more fuel. [48] By 1945, Ford made 70% of all B-24s in two nine-hour shifts. A heavily loaded B-24 was difficult to fly at speeds of less than 160mph (260 km/h). Being on long-distance patrols, they generally flew outside the range of enemy fighters. At an altitude of 900 metres there was a tremendous explosion. The B-24's controls were heavy, especially if the control rigging was not properly tensioned. The bomber had disintegrated. The turret proved unsatisfactory and was soon replaced by a tunnel gun, which was itself omitted. The B-24 was rapidly phased out of U.S. service, although the PB4Y-2 Privateer maritime patrol derivative carried on in service with the U.S. Navy in the Korean War. The B-24D was the first mass-produced series. As early as 1942, it was recognized that the Liberator's handling and stability could be improved by the use of a single vertical fin. [49] Up into December 1944, Ford had also produced an additional 7242 KD or 'Knock Down' Kits that would be trucked to and assembled by Consolidated in Ft. Worth and Douglas Aircraft in Tulsa. These aircraft became known as Judas goats.[34]. Also, most naval aircraft had an Erco ball turret installed in the nose position, replacing the glass nose and other styles of turret. A B-24 could reach 290 miles per hour and carry a 5,000-pound bomb load for 1,700 miles, giving it a longer range, greater speed, and a bigger payload than its B-17 cousin." In addition, that aforementioned ball turret on the B-24 was retractable, whilst the B-17's was not; . After the transfer of the B-29s, the C-109s were reassigned to the Air Transport Command. NOTES: Shapes below depict aircraft from wingtip-to-wingtip / nose-to-tail assuming aircraft are being viewed from overhead perspective (the nose pointing towards the top of the screen). The B-24 was a faster plane having a greater range and payload capacity. It entered US service in early 1942. Avro Lancaster Boeing B-17 Flying Fortress Range (km) 4,070 3,220 CEILING 24,508 ft (7,470 m) [Diff.-11,089 feet] CEILING 35,597 ft (10,850 m) [Diff.+11,089 feet] Avro Lancaster Boeing B-17 Flying Fortress Ceiling (m) 7,470 10,850 ARMAMENT STANDARD: 2 x 0.303 caliber (7.7mm) Browning machine guns in nose turret. While aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. Lindell Hendrix, later a test pilot for Republic Aviation, flew B-24s for the Eighth Air force. Later versions started at 60,000lbs and by the end of the war, using special flying techniques that had been developed they were being flown at up to 67,000lbs. This new fuselage was intentionally designed around twin bomb bays, each one being the same size and capacity of the B-17 bomb bays. Due to deferments of the US requirements, the US purchase was twice postponed, and the serial numbers were changed to 40696 to 40-702. [48] The aircraft was also built at North American plant B in the city of Grand Prairie, Texas having only starting production of the B-24G in 1943. [24][25], For 12 months, No. Lastly, unlike a typical purpose-designed transport, the B-24 was not designed to tolerate large loading variations because most of its load was held on fixed bomb racks. By the end of the conflict, over 18,500 B-24s had been constructed making it the . Helicopter widths include main rotor diameter. Cost: $276,000 Serial Number: 42-32076 PERFORMANCE Maximum speed: 300 mph. We have invested in developing and demonstrating hypersonic technology for over 30 years. Australian aircrew seconded to the Royal Air Force flew Liberators in all theatres of the war, including with RAF Coastal Command, in the Middle East, and with South East Asia Command, while some flew in South African Air Force squadrons. In the Pacific, to simplify logistics and to take advantage of its longer range, the B-24 (and its twin, the U.S. Navy PB4Y) was the chosen standard heavy bomber. Robert B. In some groups an observer officer flew in the tail position to monitor the formation. We develop laser weapon systems, radio frequency and other directed energy technologies for air, ground and sea platforms to provide an affordable countermeasure alternative. 540 ft/min [Diff.-49,460 feet] Boeing (McDonnell Douglas) F-15 Eagle Boeing B-17 Flying Fortress RoC (ft) 50,000 540 540. This model introduced self-sealing fuel tanks, a 2ft 7in (79cm) plug in the forward fuselage to create more space for crew members and, more vitally, ever more equipment such as ASV Mark II radar (anticipated early in the Liberator's development when Reuben Fleet told the engineering team he had a gut feeling the nose was too short). As early as 1938, the US Army Air Corps realized that if it went to war with another world power, the B-17 was be too small for long range bombing missions. The B-24H saw the replacement of the glazed 'green house' nose with a nose turret, which reduced the B-24s vulnerability to head-on attacks. ". This wing was highly efficient allowing a relatively high airspeed and long range. [13] For some time, newspapers had been requesting permission for a reporter to go on one of the missions. The design was simple in concept but, nevertheless, advanced for its time. Fifteen of the 15th AF's 21 bombardment groups flew B-24s. 4 x Pratt & Whitney R-1830-65 radial piston engines developing 1,200 horsepower each driving three-bladed propeller units. The U.S. Army Air Corps awarded a contract for the prototype XB-24 in March 1939, with the requirement that one example should be ready before the end of the year. BY ba97 - Sat May 15, 2004 9:04 pm. Later modifications gave it a single tail and yet another type of engine packages bring it to near C-87C configuration. Giorgerini, Giorgio (2002). The Liberators made a significant contribution to Allied victory in the Battle of the Atlantic against German U-boats. The single fin did appear in production on the PB4Y Privateer derivative.[10][11][12]. Intercepted just short of the target, the B-24 came under attack from JG1's Messerschmitt Bf 109s. B-17 wing . Its lower altitude made it more vulnerable to flak. Three more 0.50 caliber (12.7mm) machine guns brought the defensive armament up to 10 machine guns. Deep raids were called off in mid-October 1943 and were not resumed until February 1944, when long-range escort fighters such as the P-51 Mustang became available. Early Royal Air Force (RAF) Liberators were the first aircraft to routinely cross the Atlantic Ocean.
