Le Nakajima Kikka \u00e9tait un chasseur \u00e0 r\u00e9action exp\u00e9rimental japonais, con\u00e7u, \u00e0 la fin de la Seconde Guerre mondiale, par Kazuo Ohno et Kenichi Matsumura.<\/p>\n\n\n\n

L’int\u00e9r\u00eat du Japon pour les avions \u00e0 r\u00e9action s’est accru en septembre 1944, lorsque l’attach\u00e9 de l’air japonais \u00e0 Berlin a envoy\u00e9 un grand nombre de rapports d\u00e9taill\u00e9s sur le programme de chasseur allemand Messerschmitt Me262.<\/p>\n\n\n\n

Sur la base de ces informations, la marine japonaise ordonna \u00e0 la soci\u00e9t\u00e9 Nakajima de concevoir un appareil similaire mais avec des exigences plus modestes (vitesse, charge, etc…) car la capacit\u00e9 industrielle japonaise n’y \u00e9tait pas pr\u00e9par\u00e9e.<\/p>\n\n\n\n

Les premi\u00e8res \u00e9tudes du Nakajima Kikka pr\u00e9voyaient l’utilisation d’unit\u00e9s TSU-11<\/a> de 440 lb de pouss\u00e9e, bas\u00e9es sur les principes de Campini et utilisant le moteur \u00e0 piston Hitachi Hatsukaze (vent frais) pour entra\u00eener un compresseur \u00e0 soufflante canalis\u00e9e.<\/p>\n\n\n\n

Cependant, \u00e0 un stade avanc\u00e9 de la conception, le Tsu-11 a \u00e9t\u00e9 abandonn\u00e9 au profit du turbor\u00e9acteur \u00e0 flux centrifuge Ne-10 (TR-10<\/a>). puis NE-12 (TR-12), qui ajoutait un compresseur axial \u00e0 quatre \u00e9tages \u00e0 l’avant du Ne-10.<\/p>\n\n\n\n

La premi\u00e8re maquette du Kikka a \u00e9t\u00e9 inspect\u00e9e par des officiels de la marine le 28 janvier 1945, mais les performances estim\u00e9es avec le turbor\u00e9acteur NE-12 n’\u00e9taient pas impressionnantes, et il a \u00e9t\u00e9 d\u00e9cid\u00e9 d’effectuer un autre changement de moteur, en rempla\u00e7ant le NE-12 par l’Ishikawajima NE20<\/a> .<\/p>\n<\/div>\n<\/div>\n\n\n\n

The prototype commenced ground tests at the Nakajima factory on 20th may 1945, and on 25th june the first Kikka was completed. The following month it was dismantled and delivered to Kisarazu Naval Air base where it was re-assembled and prepared for flight testing. Ground tests continued on this airfield until 13th July.<\/p>\n\n\n\n

On the 7th August 1945, Lieutenant Commander\u00a0Takaoka Susumu<\/a>\u00a0made the first flight, with a duration of 11 minutes. His take-off run of 2,380 ft. took 25 seconds at an all-up weight of 6,945 lb. Wind speed was 23 ft.per second. He landed in 3,280 ft.<\/p>\n\n\n\n

A ceremonial official “initial” test flight was made on 11th August, four days later. For this flight, rocket assisted take off (RATO) units were fitted to the aircraft. However, because their alignment had been miscalculated, The acceleration was so heavy that the nose of the aircraft came up, the tail went down and skidded along the runway. As a result the aircraft did not take off at all and was damaged when it ran off the end of the runway.<\/p>\n\n\n\n

Before it could be repaired Japan had surrendered and the war was over.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Le Kikka du NASM<\/h3>\n\n\n\n

The National Air and Space Museum<\/strong> (NASM) poss\u00e8de le seul exemplaire connu de l’avion \u00e0 r\u00e9action exp\u00e9rimental japonais Nakajima Kikka<\/strong>, con\u00e7u \u00e0 la fin de la Seconde Guerre mondiale. Cet appareil a \u00e9t\u00e9 assembl\u00e9 \u00e0 partir de pi\u00e8ces provenant des 25 Kikka pr\u00e9-production en cours de fabrication \u00e0 la fin de la guerre.<\/p>\n\n\n\n

Bien que les syst\u00e8mes internes de l’appareil soient incomplets, l’avion a \u00e9t\u00e9 en grande partie restaur\u00e9. Le train d’atterrissage, qui avait \u00e9t\u00e9 endommag\u00e9 lors de la sortie de piste du pilote d’essai Takaoka Susumu<\/strong> lors du deuxi\u00e8me vol, ne montre plus de traces de ces dommages. Le mus\u00e9e dispose \u00e9galement de deux moteurs Ne-20<\/strong>, qui pourraient \u00eatre utilis\u00e9s lors de futures restaurations pour reconstruire l’avion.<\/p>\n\n\n\n

The Kikka<\/strong> du NASM est expos\u00e9 au Steven F. Udvar-Hazy Center<\/strong>.<\/p>\n\n\n\n
