Parece un Yak-3.
Conozco el He-112 es un mucho mejor aeroplano que el Bf 109, no? Especiales en 1935.
Uno de los buenos enlaces que puedes encontrar en mi país acerca de este avión: Heinkel He-112
En teoria si, pero sufrio de algunos problemas de desarrollo y estabilidad como podras haber leido.
Es bueno pero el mio es mas largo ( del topic estoy hablando) despues pondre algo sobre el He-112 en Alemania y España.
and a lower wing loading that led to easier landings and better maneuverability. By contrast, the Bf 109 was 30 km/h faster than the He 112 in level flight, and superior in climbing and diving
FROM OUR CORRESPONDENT BERLIN, MARCH 31 It is claimed that Flight Captain Dieterle, flying a Heinkel aeroplane last evening at Oranienburg, near Berlin, broke the world speed record by covering a measured: stretch of three kilometres (1.86 miles) at-a speed of 746.66km. an hour (about 463.8 miles an hour). The machine in which this speed was attained was a one-seater fighter which incorporates the latest improvements on the He.112 U type, in which General Udet established a. speed record over a distance of 100 kilometres (62.13 miles) last year. The machine. is, driven'by a Mercedes-Benz engine developing 1,175 h.p. The' former speed record was esta- blished in 1934 by Warrant Officer Agello. of the Italian Air Force, with a speed of 440.6 m'iles an hour. 463 M.P.H. GERMAN CLAIM TO AIR SPEED RECORD
Extract from The Luftwaffe War Diaries by Cajus Bekker, published today by Macdonald at 63s. A narrative based on the collated Luftwaffe diaries, none of which has yet been published outside Germany. Shortly before 08.00 on July 18, 1942, an aircraft waited at the extreme end of the runway of Leipheim airfield, near Gtinzburg, on the Danube. The runway was only 1,200 yards long, and every yard was needed. Fritz Wendel, flight captain and chief test pilot with Messerschmitt, acknow- ledged the farewell wishes of the men on the ground with a nod of his head. and closed the roof of the cockpit. The sound of the engines rose to an ear- splitting scream. On this machine the traditional feature of every other aircraft to date was miss- ing: the propeller. Nor were the engines themselves of the conventional type. Instead, beneath the wings were two thickly cowled jet turbines. Slowly and cautiously Wendel pushed forward the power-lever. With both feet on the brakes he held the plane for 30 to 40 seconds, till the revolution counter read 7,500. Eight thousand five hundred represented full power, and he could hold it no longer. With its sharp nose pointing into the air, the machine resembled a projectile. This position had the effect of blocking the pilot's forward vision. He could only keep aligned with the runway by glanc- ing to the side. On the initial take-off of a revolutionary prototype this was a dis- advantage indeed. If only. thought WendeL it had a tricycle-undercarriage. Its undercarriage was, in fact, the only conventional thing about the plane. It accounted for its awkward stance, as a result of which the blast of the engines hit the ground and the pilot could not see. Worse, the tail unit in this position was aerodynamically " blind ": it re- ceived no air-stream. There was no re- sponse from the elevator and for all its high ground-speed the machine refused to become airborne. Then Wendel put fortune to the test. He had been advised as to how, in such a situation, he could still get the stub- born tail into the air. It was a most irregular and dangerous procedure, but he had to risk it. At 110 m.p.h. and full power, he suddenly trod briefly but sharply on the brakes. It worked. The plane tipped forward on its axis, and the tail came clear of the ground. Hori- zontal motion at once produced an air- stream, and at last pressure could be felt from the elevator. Wendel reacted swiftly. Very gently, almost auto- matically, he lifted the aircraft off the ground. The first Me 262 was airborne-and how it flew ! The chief test pilot, who had nursed it from the beginning, was at last rewarded for all his trouble. He pushed the stick a bit forward to gain more pace, and felt himself pressed backwards into his seat. The Messer- schmitt shot like an arrow up into the sky. What was more, the higher it climbed, the faster it flew. The astounded Wendel stared at his inst-u- ments. Since he himself had raised the absolute world speed record on April 26, 1939, to 469.22 m.p.h. with the Me 209, it had only been exceeded by his colleague Heini Dittmar in the rocket- propelled Me 163.
TEST DISASTER Now the third prototype of the Me 262, with its twin Jumo 004 jets, was soaring above the world-record mark on its very first flight, 500 m.ph. on the clock, without a murmur I Suddenly Wendel felt really happy in this sensa- tional aircraft. He throttled back, then reaccelerated: the engines responded splendidly. Then in a wide circuit he swept in to land, put down smoothly, and rolled to a stop. The first flight of the Me 262 V-3-the world's first jet aircraft ever to reach the stage of series production-had lasted just 12 minutes. After the tenth flight, during which the plane reached well over 500 m.ph.. he advised the factory management to get ready for serious production. Such a decision could not, of course, be taken by Messerschmitt alone. Till now the contract had only been for three proto- types, nothing more. So the supply chief in Berlin-Milch-was put in the picture, and he in turn set the wbeels turning at the official Rechlin test centre. On August 17, just one month since the M4e 262's initial flight, there arrived from Rechlin an experienced test pilot, in the shape of staff-engineer Beauvais, to submit the new plane to exhaustive trials. As he edged himself into the narrow cockpit, Wendel reminded him once again of the trick with the brakes to elevate the tail. He himself would take up station at the 800-yard mark to indi- cate when Beauvais should execute this manoeuvre. Then he watched as the machine approached. But its speed was too low-nothing like 110 m.p.h. None the less, as he came abreast the pilot braked. The tail-wheel came up, but then fell impotently down again. Beauvais tried it a second time, then again just before the airfield perimeter. Sornehow the machine became air- borne, and whizzed over the ground at perhaps 3ft.-but much too slowly ever to gain height. Seconds later a wing-tip touched a refuse heap, and with a loud report the Messerschmitt crashed on top of it in a cloud of dust. Miraculously the pilot climbed out of the wreckage almost unscathed. This accident put back the Me 262's final development by months. The first German industrialist to give play to the new propulsion ideas was Ernst Heinkel. At the end of 1935 he had a meeting with the young Wermher von Braun, who was then still experi- menting with so-called " rocket-stoves " at Kummersdorf firing range, near Berlin. Braun was convinced that rockets could also be used as aircraft propellants. Heinkel accordingly sent him the fuselage of an He 112 for bench experiments, together with a few aircraft technicians. With the arrival of test pilot Erich Warsitz from Rechlin the hazardous enterprise could begin. INFERNAL NOISE With an infernal noise, Braun's rocket motor, mounted in the He 112 fuselage. was fired off and its attendants cowered behind a concrete screen. Several times the combustion chamber exploded, and twice Heinkel had to send a replacement fuselage. There followed a whole plane, complete with its standard engine. The rocket engine was added, but Warsitz w.s only to ignite this after becoming airborne. However, during a preliminary run-up on the ground the whole He 112 blew up and the pilot was catapulted through the air. Instead of giving up, Warsitz per- sonally asked Heinkel for a new plane. With this, in the summer of 1937, the first rocket-powered flight was made. The He 112 shot heavenwards, circled the airfied and landed undamaged. Heinkel then proceeded on his own initiative to develop the He 176, an air- craft specially designed for a rocket power-unit. Meanwhile the chemical specialist Dr. Hellmuth Walter had been developing, at Kiel a more regular type of rocket engine with a thrust of 1,2001b. which was considerably more reliable than Braun's " rocket-stove ". Equipped with this Walter engine, the He 176 was sub- jected to its first runway tests on the shore of Usedom Island, in the Baltic, and in the spring of 1939 they were con- tinued by Warsitz at Peenemtinde. Eventually on June 20, 1939-a calm day witb good visibility-the time had come for Warsitz to make up his mind. His determination infected the fac- tory engineers, despite all their warnings and forebodings. They watched as the He 176 raced down the runway, hit a small unevenness, and inclined danger- ously to the side. But Warsitz kept con- trol, righted the spitting little monster, and finally lifted it closely above a wood near by. On the previout runway tests he had been obliged to curb all acceleration, but now as the aircraft soared to freedom he was tightly com- pressed against his supports. In a few seconds he had been carried far out over the Baltic-and it was already time to turn back and relocate the airfield. In spite of this stIccess the He 176 was rejected and though Heinkel fought the decision, and arranged a demonstration before Hitler and Goering, more interest was shown in the achievement of the pilot than in the epoch-making little machine. The aero-engine industry had other worries. The Luftwaffe was arming at breakneck speed. and if the still appre- ciable lead held abroad in piston engines was to be caught up with, there was no time to start playing about with imn- mature theories. Only late in 1939 was a development contract for a turbo-jet engine granted-to Junkers at Dessau and B.M.W. Messerschrnitt was to design an airframe for it. POTENTIAL REALIZED Thus HeinkeL whose own initiative had put him a good step ahead, was by-passed. It did not upset hirn; he juSt carried on, determined as ever to show the "Berlin gentry" what he could do. Ohain's first turbine had been running since September. 1937, and a year later he had produced a more powerful one, which in summer, 1939, was fitted to the He 178. So it came about that Fligbt Captain Erich Warsitz, a few weeks after flying the first rocket aircraft, also flew the world's first jet aircraft. That was on August 27, 1939, just five days before the war started. Thus in Berlin no one had time for the He 178. and it was not until the Polish campaign had been over for weeks that Heinkel succeeded in demonstrating his brain-child before Milch and UdeL Goering did not bother to attend. After an initial false start the plane s^wept over their heads deafening them with its howling turbine and thundering its message home. But the leaders of military aviation were already dazzled by the Luftwaffe's swift victory in Poland and to short-sightedness was added arrogance. " Before that comes to anything, the war will have long since been won.... " On May 22, 1943, almost a year after Wendel had first flown it, interest in the Me 262 jet fighter was revived only after it had been flowfi by the 31-year-old fighter leader Adolf Galland. He was most impressed. If only, he thought, he could equip his fighter units with such an aircraft soon enough, and in sufficient numbers, the Battle of Ger- many need still not be lost. At once he reported to Mitch and Goering. The Me 262, he said, was a project of prime importance. It could turn the tables and the tide. He seemed to have convinced the two of them. Yet even now series production did not begin, for one man was agairnsti-t: Hitler. He did not want a new fighter. He did not want defence: only attack. He wanted bombers, nothing else. When on Nov- ember 26, 1943, after a further six months of delay, the Me 262 was demonstrated at Insterburg in his presence, he astonished Professor Willi Messerschmitt with the question: "Can this aircraft carry bombs?" Messerschmitt said yes-so could any aircraft in the last resort. Then he hesi- tated, thinking about the implications. . . . But Hitler did not let him utter another word. "So there at last is our blitz-bomber ! ", he cried triumphantly. The people about him were stunned to silence. It had suddenly become one of Ihe Fuihrer's " irrevocable resolves ", and no subsequent protests changed it. The world's first jet fighter was to be weighed down with bombs. Its superiority was gone. Hitler's gambit-to turn the first jet fighter into a bomber-was yet another example of his " intuition " upsetting the applecart. ? Macdonald Co., and Tines News- papers Ltd., 1967.
