Thomas-Morse MB-3

The most successful american single-digit fighter of the postwar period, which were equipped with all the fighter squadron of the u.s. army at the beginning of the 20. years, he was the type of , the Thomas-Morse MB-3, designed by british immigrants B. D. Thomas (with the brothers Thomasovými, the company's founder, was not a relative, it's just a name match, even though they were also British). In 1918, there were three american airlines-invited for the construction of prototypes, inspired by the successful spad, with dvoupříhradovou structures of the wing with the profile of the RAF 15, the engine of the Wright-Hispano and two 7.62 mm machine guns and a sight Aldis. 27. September was ordered , the Thomas-Morse MB-3, 11. October Lewis & Vought VE-8 and four days later the prototype Orenco D. Construction of the MB-3 was a conventional all-wood, ailerons only on the upper wing, where it was also cooler and třígalonová catchment tank. The space in the fuselage was very cramped, so the instruments were scattered throughout the space, instead of being on a single board. Two additional tanks were located in the fuselage, osmnáctigalonová front of the pilot and dvacetigalonová in the rear part of the fuselage. In the for its time very aerodynamic bow were placed two 7.62 mm machine guns Marlin. The propeller was fitted with a metal cone.

The first of four ordered prototypes, AS40092, was brought to McCook Field in Dayton for static tests, the second was a [21. February 1919 at the corporate airport in Ithaca and now has created an unofficial record of the military machine reached the speed of 270 km/h and the ascent to 3048 m in 4 minutes and 52 seconds. This prototype got from the Flight Test Section was allocated the designation P-66 and after a year of 1921 was eventually dismantled for spare parts. P-124, therefore AS40094, was damage has occurred during shipping, although was corrected, but 30. April 1921 was destroyed in a crash. The prototype P-121 with the number 40095 had more luck and survived until October 1926. Test pilots, however, poorly assessed the views and the lack of space in the plane. The problem was also with maintenance and also with the corrosion caused by leaking tanks. The added complication with a heatsink and vibration from the engine. Therefore, on the P-121 extended the cockpit, slightly shifted the radiator and the volume of the tank in the wing enlarged to 12 gallons. Also has reinforced construction, which has had a mass of 590 kg. Also was reduced kýlová area.

The army ordered 19. June 1920 50 such modified machines that were given the serial numbers 63331 up 63380 and the first were completed in November. Four of the machines of the army ended up on the McCook Field and tried them the other adjustments, such as further amplification of the structure and move the radiator to the sides of the fuselage. At this time were all military projects of the law the property of the army, so that to decide who gets the contract to another machine. In February 1921 showed interest in the construction of the 200 additional machines according to these four, in addition, with armament changed to one 12.7 mm and one 7.62 mm machine gun Browning in the bow, and the offer submitted by nine companies, including Thomas-Morse and Curtissu, but the contract was awarded to the firm Boeing, which offered the prize to 7279 dollars a piece. This contract included in the price of almost one and a half million dollars Boeing gained a solid foundation for the future, and also has acquired the technology, which he later used in the manufacture of its successful series of fighters PW-9 and P-12. This loss and the failure of other projects, as was XP-13 Viper, more recently a thriving company Thomas-Morse substantially exhausted, until the end of the 20. years become mere divisions of the company Consolidated and eventually disappear completely.

To Seattle was the army sent one of the four experimental MB-3, AS63332 as a sample piece, however, was poškozem when landing. The first of the Boeing-built machines, which were given the designation MB-3A, took off 7. čevna 1922 at Camp Lewis, but when a landing is the influence of unevenness on the track turned over on his back. However, THIS was not to zakázků no effect and all machines were delivered between 29. July and 27. December 1922. On all machines it was possible to use both the original dvoulisté, and new čtyřlisté propeller, introduced because of the drive down the vibration, and the last fifty machines also received a new tail surfaces proposed by the army. After they have been in provoliniové service replaced by Boeing MB-3A were some MB-3 adjusted to a advanced trainer aircraft MB-3M, which continues to serve on the texas the Kelly Field at 43. training squadron (43rd School Squadron) and were scrapped in 1929. All eight of the fighter squadrons this time was armed with aircraft MB-3A - four of them accounted for 1. fighter group, which had from 1. July 1922 to 8. December 1941 their base on the Selfridge-Field in Michigan, the other two squadron were located in Hawaii, one in the Philippines and one in the area of the panama canal. After 1926, when the standard fighter of the USAAC became the Curtiss Hawk, many of the MB-3A rebuilt in Fairfield Air Intermediate Depot, and moved to the Kelly Field and come to an end as a practice. Boeing also created the design of the machine, extended by two feet, and with ailerons on the upper and lower wings, but was not adopted.

MB-3 and MB-3A they were also used for air racing, for the first time in 1920, when the prototype of the MB-3A won the captain Harold E. Hartney second place in the Pulitzer Trophy, and raced here and lieutenant Leigh Wade, which of course ended after the first round. MB-3 the two versions of the run up to the year 1923. 24. march 1921 he received the Thomas-Morse order on the three racing specials MB-6, coming from the MB-3, but differing with short span and length and the engine of the Wright H-2. All were transported to the McCook Field and then, what was the one used for the static tests, by captain John And. Macready 21. October 1921 the first flight of this type, that was about four days later this machine destroyed in the crash. The remaining MB-6 was renamed on R-2 and transported directly to Omaha, where, controlled by captain Macreadym, won the second place in the Pulitzer Trophy with a speed of 258 km/h. R-2 was used by the army until 1924, when he was 31. October scrapped.

Thomas-Morse received 16. march at least a contract for twelve MB-3 for the marine corps, which was then adjusted to ten MB-3 and two MB-7, which was another racing modification, this time in the form of a high wing aircraft with so-called wing, Alula, in the middle and on the edges of the thin, with ridges in the middle of the leading edge. First of MB-7 took off 24. October 1921 in Ithaca, but was then destroyed in the race due to a failure of the pump. The second machine was completed in February 1922 and, unlike the first, which had the engine of the Wright H-2, had the Wright H-3 about the same performance. [He was 14. in may 1922, but did not meet the embedded hope, when he participated in the race in Detroit ended prematurely because of přehřátému engine. Then ended up in storage Naval Aircraft Factory in Philadelphia, until he was in march, 1925 scrapped. Instead of the first MB-7 was built in the eleventh MB-3 for the marine corps, which was, together with the other delivered to the base of the marine corps in Quantico in February 1922, and were deployed with the 3rd Marine Air Squadron. Already a year later ae were discarded and handed over to the army air force on the , Langley Field. In the year 1927 found a few more MB-3M and MB-3A your use at McCook Field during the filming of the movie Wings, which have played a role spadů , and even German aircraft, and some of them were for the purpose of filming and destroyed. Thomas-Morse continued to develop, however, on the way MB-7, therefore, high-wing parasol. Thus was formed the trinity closely downstream of the types of racing R-5, fighter MB-9 and a practice MB-10, but did not mass-production.

On Youtube I managed to track down the scene from the film Wings from 1927, in which, as already mentioned, the role of many aircraft, the French, british, and German origin played is MB-3. In this scene, an american pilot David Armstrong (actor Richard Arlen) steals a German plane (played perhaps Boeing PW-9/FB-1) and try to fly on the allied side of the queue when it is attacked by allied fighter (accounted for by the MB-3A with high kýlovkou) pilotovaným armstrong's friends and rival, Jack Powell (Charles "Buddy" Rogers), who considers him to be just "another enemy to blast".

I'll allow myself a bit of a dig at the lovely American filmmakers.
A pilot in a flying machine with no protection could certainly not have his hair lightly brushed by the wind, but in a few minutes or so his face was completely drenched in tears up to the back of his neck and he saw absolutely nothing. Besides, he would have been in for a hell of a minimum of conjunctivitis and probably worse. And besides - only the truly fiercest scalp hunter wouldn't back down if the pilot of the pursuing machine didn't just throw up his hands and make it so clear that he was surrendering. Such cases are documented. But then again, one couldn't miss the sight of heartfelt cries for a friend and all that other milking. And the fact that the pilot is riding in a completely different machine in the side view than in the front view is just the icing on the cake. I guess the filmmakers had a limited budget and didn't get some unemployed former war pilot to keep an eye on these "typos" Cool .

The music was probably used by the depositor on the !trumpet", and he used a very nice one, fitting the story. Praise him!
