Suitable for Ages 10 & Older. Ziegler pulled up and off the course and bailed out of the Q-2A. See more ideas about wwii aircraft, ww2 aircraft, fighter planes. The lack of hydraulic boost on Japanese aircraft controls meant their maneuverability suffered at speeds near or above 300 m.p.h. With just military power, the Q-2 recorded a speed of 407 mph (655 km/h) at 24,000 ft (7,315 m) and a climb rate of 3,210 fpm (16.3 m/s) at sea level. attempt. Developed from the P-36 Hawk, it performed its maiden flight in October 1938 and was retired in 1958. – Vee is for Victory by Dan D. Whitney (1998) The XP-40Q-1 was the first aircraft, and it was built in 1943 from a P-40K-10 (serial 42-9987) that had been damaged in a landing accident on 27 January 1943. The Q-2A had a natural metal finish. The Q-2A was very similar to the final configuration of the Q-2—with a bubble canopy, clipped wings, and -121 engine. This aircraft later had anti-glare paint applied to the upper cowling, its serial number painted on the the tail, and “12” painted on the chin scoop. oh yes, I had forgotten, Kermitt Weeks is restoring a Fury V powered by a 2,400 hp Sabre. with 4 20mm cannons, 1425 hp422mph at full chat, yeah ! At Hobby and Toy Central we take great pride in the quality of our products and service. Extremely high exhaust temperatures prevented further development as it came late in the war. (The 1649 was a gorgeous looking plane, though I have never seen it in person) Also the Oscar and more so the zero could not turn right worth beans at full power at any speed. Playtest v1. The P-26 was a mo… As a result, the Army Air Force (AAF) focused on the next aircraft, the Q-3, and loaned the Q-2A to Allison for engine tests. These v-12's produced some serious 'grunt'. paint on the spinner by Curtiss P-40Q - 72nd Aircraft however, had events taken place sooner she may have seen the light of day. Curtiss and Allison both made a concentrated effort to improve the P-40, and for all intensive purposes, i’m of the belief they I believe the ” Jug ” was very effective at curtailing the LW. Merlin V1650. she could rollwith best of them, dive like brick, and dish out a beating as well as take a pounding that would finish off others, yet more often that not, return to base. The aircraft was repaired and then sent to Wright Field, Ohio in mid-1944. Other than some paint, including its registration and race number, the aircraft had changed little since its AAF days. Free shipping. The Q-2A most likely had the same specifications and performance as the -121-powered Q-2. This also happened with Tsunami: the aircraft went faster when the power was pulled back a bit. Learn how your comment data is processed. Note the size of the bubble canopy and how to could be a bit smaller. Rescued and the hulk was eventually purchased by Allan Arthur and exported to Australia. The shorter and deeper nose of the new fighter gave it a decidedly snub-nosed appearance compared to the earlier P-40 models. By mid ’44, many of the top LWP’s were dispatched to see Jesus ! The Q-3 had a -121 engine and a natural metal finish. They all had only four .50-cal machine guns with 235 rpg. The oil cooler and engine air intake were relocated to the classic P-40 chin position, but the scoop was shallower and more elegant. production was undertaken. ( Log Out / The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. That would make for one screamin' hawk !it's all good. This image of the XP-40Q-2A illustrates the clipped wings. High quality Curtiss P 40 gifts and merchandise. Only 283 of those engines/cases were built, and maybe 19 cases exist today. XP-40Q development was initiated by 1943. Curtiss P-40Q 1940 Prior to the final termination of P-40 development, some effort was expended in combining aerodynamic refinement with increased power to produce a higher-performance model. US only real jack plane, the P-40. I'verecently come by some images of a dyno cell at Allison.Some h.d. – Curtiss Fighter Aircraft by Francis H. Dean and Dan Hagedorn (2007) Note: There is no indication that any of the XP-40Q aircraft used any type of a laminar flow wing. Roughly twice the operating andpurchase price of equivalent poppet valve engines. angels 20 could be attained in 4.8 min. A second, similarly re-engined There is also no indication that any XP-40Q information was passed from Curtiss to North American Aviation (NAA) during the NA-73X’s (P-51’s) development. Whether known as the Warhawk, Tomhawk or Kittyhawk, the Curtiss P-40 proved to be a successful, versatile fighter during the first half on WWWII. It is not clear if the aircraft suffered another accident, or if Curtiss was unhappy with its configuration and decided to modify it further. Reason for not chancing a flight? The P-40N was considered the best of the breed. The Curtiss P-40 Warhawk was an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. It was vastly superior to earlier variants of the Hawks lineage, and surely The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. The company’s final two truly successful aircraft, the P-40 Warhawk fighter and C-46 Commando transport, had already flown. 1942, Curtiss P-40 Tomahawk and Kittyhawk were introduced. either six 12.7mm or four 20mm weapons. In 1933, however, Boeing had beaten Curtiss in competition for a lucrative Army fighter contract with its innovative P-26 Peashooter. h.p. The Q-1 was painted olive drab and had the standard P-40 wing and canopy. In aircraft engines Horse Power is converted to the desired"torque" and thrust by gear reduction and controllable propeller pitch. Experimental & Prototype Aircraft Projects: Fighters 1939-1945 by Bill Norton (2008) Merlin V1650 as used in the P51D, and results showed a better airplane than both the ME-109 and Spitfire. The XP-40Q-1 was the first aircraft, and it was built in 1943 from a P-40K-10 (serial 42-9987) that had been damaged in a landing accident on 27 January 1943. This was easily compensated for at low speeds but at over 250 mph they were at full or nearly full power.As far as I know no version of the P-40 had flight control boost. P-40E-1CU 41-36084 RAF Kittyhawk Ia ET730 Polly Australian War Memorial. It is truly unfortunate that the aircraft would soon be destroyed as a result of an engine fire. Card Kingdom 589.12 - 621.60 . The nose of the aircraft was lengthened to accommodate the V-1710-101 (F27R) engine. 1:72 Curtiss P-40 Warhawk Timeline for AMC Models (CZ) (7205) Curtiss P40 Q-2 Full timeline I simulated the "wear" of the O.D. It is doubtful that much performance testing was conducted on the Q-3, but the results should have been similar to those of the Q-2. add h2o /meth injection and you have a 20% boost in h.p. The Q-3 was built in early 1944 from a P-40N-25 (serial 43-24571) and was the only XP-40Q actually classified as such by the AAF. that's a r.o.c of 4,167ft /min. A study was done and it wasdecided a two stage Merlin powered P-40 would have rivaled a Spit, Bf-109 or P-51 but none ever flew.The P-60 proved the concept to be a fantasy.BorisThe. Thanks for the reminder. as for the p-40q. allison usedsupercharger ratios from a low 0f 6.00:1 with a mix ofratios, topping out at 9.:80.1 . However, some modifications to the cockpit and canopy were made, and automatic radiator and oil cooler shutters were added. A P-40K airframe was fitted with an With full engine power at 3,000 rpm and water injection, the aircraft achieved 420 mph (676 km/h) at 15,000 ft (4,572 m) and had a maximum climb rate of 4,410 fpm (22.4 m/s) at 5,000 ft (1,524 m). Ever heard of the Napier Sabre IV 24 cylinder sleeve valve 3500 horsepower no more frontal area than a Merlin and barely 8 ft long the Napier would have made this kite go some, Fue una hermosa maquina de limpia arquitectura americana Literalmente una joya de la mecanica. Gustav Lundquist had evaluated the Q-2 and judged it to be the best P-40 he had flown; he recommended that further flight testing should be conducted. Curtiss fell short in their Deemed inferior for use as fighter in Europe, they were sent to the desert where they could counter most of the Italian fighters, although they could not be mached to German Bf-109E and F..." she was the only fighter that could turn with the a6m zero. The four .50-cal wing guns are easily seen. good answer. – U.S. The Curtiss P-40 Warhawk was developed and manufactured by Curtiss-Wright Corporation as a single-engine all-metal fighter and ground-attack aircraft during the late 1930s. The problem with Curtiss Wright was upper management, dominated by bankers and accountant. Note the oil cooler exit doors on the cowling just in front of the wing. Note the radiators and oil coolers mounted in the wing center section. In December 1943, the Air Materiel Command recognized the XP-40Q-2’s performance and recommended that two additional prototypes be constructed. a move known as low yo - yo.

The Curtiss P-40 Warhawk was a WWII fighter aircraft that was developed from the P-36 Hawk, via the P-37. ( Log Out / It was thought that the improved performance of the P-40Q would justify the aircraft entering production, and its similarities with P-40s then being produced would minimize tooling and production delays. This is the old Pegasus (UK) kit of the ultimate P-40, the one many mistake for a Mustang. It was the third most-produced American fighter of World War II, after the P-51 and P-47; … The P-40 was the product of a long development process that began when the USAAC invited various aircraft companies to submit designs for its 1935 fighter competition. Boring.Everyone talks about the P-51 Mustang, the beginning of WW2, was the only one attack aircraft named A-36 Aptche. there was a u.s. gen. who once said" the p-40 was damned bywords, but was flown into glory".i have not been able to find out who this general was, however i feel he was right.the p-40 was a much better a /c than many have given her credit for. history is,as history was.

The C model Mustang tested at up to 453 mph with comparable power to the Q. Similar Deck Space Auto-suggestions. Delivered to AAF in April 1944, the Q-3 suffered an engine failure during an early test flight. The comment on revs and performance is very interesting. much was learned from this, no doubt. Boggles the mind. The XP-40Q-2A seen at Cleveland, Ohio for the Thompson Trophy Race in 1947. canopy and coolant radiators faired into the wing Tempests arrived in Feb /Mar of '45and in a short period of time did a bang up job! By the time the P-40Q prototype was flying, the Air Force was already getting all the P-38s, P-47s and P-51s it required, all of which were just as good, if not better. andis a good 4'ft in diameter. At 3,200 rpm and with water injection, maximum speed was 422 mph (679 km/h) at 20,500 ft (6,248 m), and the climb rate increased by as much as 530 fpm (2.7 m/s) depending on altitude. A brief glimmer of hope lay in the last model of the P-40, the P-40Q (Curtiss model 87X). Deckcycle Deckcycle Feature Queue. Built to USAAF order as 42-104687 but diverted to the RNZAF as Kittyhawk Mk IV NZ3215. VH-ZOC Curtiss P-40N Kittyhawk c/n 28449. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. i thinkit was in 1937, one of the supermarine a /c achieved anairspeed of 430mph, in a /c equiped with floats no less.they were on the right track, to be sure.

The XP-40Q-2 had a 35 ft 3 in (10.7 m) wingspan and was 35 ft 4 in (10.8 m) long. The XP-40Q was definitely a nice looking aircraft. The next aircraft was the XP-40Q-2A. The aircraft had balanced controls and was very maneuverable, with a tight turn radius. The legendary "reliability" of Napier's masterpiece!Boris, P-51 and that "lousy Allison"?The P-51A and A-36 were powered by an up-rated V-1710-81 that gave better performance and speed rose to 408mph@15,000'.Some say 390 mph, but I tend to believe the USAAC /USAAFnumbers at 408.To put that in perspective the A model was the best performingversion of the P-51 under 10,000' till the H model came around.Above 10,000' the two stage Merlin ruled.Boris, I think Boris just about Nailed it.A different engine doesn't make a different aeroplane. The wings are still the standard P-40 wings, but they were later clipped by about one foot. All of theengine constructors during that period used dynomometers,and the h.p. plumbing,air ducting, and the water brake washuge by large ! as for torque /thrust valuesthey may very well not exist. Top Rated Seller Top Rated Seller. What could have been ? In service to boot.Mass produced and used in everyday service....Sabres are cool, but utterly unreliable at any power setting.When WWII ended so did the Sabre, as far as i know there areNO running Sabres static or otherwise, and for good reason.The highest power output for a Sabre in regular service was the Sabre V at around 2,500-2,600 HP.Weight was decidedly piggish at over 2,350 lbs for thepower unit only.Allison weight was about 1,400 lbs depending on model.As a result Sabre installation in a P-40 would have been an impossability. Edit. The P-40’s place in history is firmly cemented. had a good driver. Post was not sent - check your email addresses! Performance was marginally better at high altitudes and worse at sea level. That one snuck past me but has been corrected now. She could turn and roll well, had a significantincrease in airspeed, diving was never really an issue,and now, she could climb! succeeded, only to have the ‘ Brass ‘ remain ignorant and blind to looking a gift horse in the Napier's 3,500HP Sabre was a running but still born project.Sleeve valve engines did not tolerate high boost pressures well at all and the Sabre at 3,500HP would likely have never survived in service. 42-9987 by Capt. The P-40Q was one of the finest fighters Curtiss ever built, but the aircraft was two years or so too late. 42-9987 by Lt Norman A.

There wasample time to sort out a half dozen or less items onthis a /c. and 1,100hp at 7620m. Three XP-40Q prototypes were built; their origins and histories have always been a point of disagreement between sources. during the depressionera, i believe g.m did little if any r & d on the allison. The aircraft’s rear fuselage was cut down and a bubble canopy installed. The ultimate Allison V1710 was the E27 variant capable of 3,000 h.p. Regardless, by November 1943, the Q-1 had been modified and redesignated XP-40Q-2. if by chance they do, i think the numbers would be interesting. rating was at 3000 rpm at sea level for takeoff. NAA did purchase some information from Curtiss at the request of the British government, but that information pertained to the XP-46 and arrived after the NA-73X was already designed. The Q-2A’s first flight occurred prior to the end of March 1944. Th eturbines are turning at 13,000RPM + but the prop is turning about 1,100 RPM.Similar for WWII era piston engines, most had a gear reduction of between 1.33:1 and 3:1As far as I know Allison V-1710s were equipped with 1.5:1 (prop turning slower than the engine) gear reduction and 7.3:1 or 8:1 blower drive ratio. clipped wing tips, the cut-down aft fuselage with bubble This view of the XP-40Q-3 illustrates the revised canopy compared to the XP-40Q-2A. They got it right on that one ! After pouring over everything I have I have found no referenceto a two stage Merlin ever being installed in any P-40.I would love to read about that, got a reference?The XP-60 started life as a P-40N and got a British built Merlin 28.That's a two stage Merlin similar to the Packard V-1650-7 used in the P-51D.The P-60 was a non performer despite having a laminar flow wing.Other engines were tried and also failed to impress before the project was cancled.The Allison V-1710-127 was a turbo compounded engine that was statictested to 2,800hp and may have been capable of more.Exhaust temps were high and corrected and a quick fix wasto ingect water into the exhaust stream to drop the tempsto the level the turbo could survive.No P-40 ever flew with a 2 stage Merlin. The XP-40Q was an in closing, we all know the h.p rating of those beautiful v-12's, works of art. the p-40, her pilots, and the g /c's did a great job. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The radiator and oil cooler were moved from the P-40’s iconic chin location to the wing center section, just below the fuselage (similar to the XP-40K). The XP-40Q-3 she’s drop dead gorgeous ! The aircraft could climb from sea level to 20,000 ft (6,096 m) in 4.8 minutes, 30,000 ft (9,144 m) in 8.9 minutes, and 39,000 ft (11,887 m) in 26.1 minutes.
