Tachikawa Ki-72

The Tachikawa Ki-72 was a design for an improved version of the Ki-36 Army Type 98 Direct Co-operation Plane. The Ki-72 would have had a fully retractable undercarriage, in place of the fixed wheels of the Ki-36, and would have been powered by a 600hp Hitachi Ha-38 engine instead of the 450hp engine used in the earlier aircraft. The Ki-72 did not progress beyond the design stage.

Tachikawa Ki-70 (Clara)

From 1941 onwards, the Imperial Japanese Army Air Force (IJAAF) relied on the twin-engine Mitsubishi Ki-46 (Allied codename of "Dinah") for fast reconnaissance work. 1,742 of its kind were produced across several major marks. In time, thought was given to pursuit of replacing this early war implement and this gave rise to the little-remembered Tachikawa Ki-70 ("Clara").

For speed, the Ki-70 was to retain a twin-engine layout mated to a well-streamlined fuselage. The nose section was heavily glazed for excellent vision with the cockpit stepped just aft. Along the dorsal spine rear was another heavily glazed section for views to the sides and rear. The crew numbered three. Rounded monoplane wings were set at midships with the tail unit consisting of a split vertical fin arrangement along a singular horizontal plane. The powerplant of choice became a pair of Mitsubishi Ha-104M engines of 2,070 horsepower output driving four-bladed propeller units. Dimensions included a length of 14.5 meters, a wingspan of 17.8 meters, and a height of 3.46 meters. Empty weight was 13,000 lb with a Maximum Take-Off Weight (MTOW) reaching 23,590 lb.

Due to the fast speeds and relatively high altitudes that the Ki-70 was required to operate at, its armament was strictly defensive in nature - centering around a modest 1 x 12.7mm heavy machine gun and 1 x 7.7mm machine gun pairing. The rear cockpit was to be a dedicated machine gunner's position.

Tachikawa managed to complete the initial prototype in 1943 to which a first flight took place that same year. The program eventually netted a total of three prototypes in all yet none were able to prove the product sound - the Ki-70 was a slower aircraft than the one it was intended to replace and handling issues were not all that favorable. By the end of the war, the Ki-70 initiative was abandoned in favor of more critical wartime endeavors.

Performance specifications for the Ki-70 included a maximum speed of 360 miles per hour, a cruising speed in the 305 mph range, a service range of 1,540 miles, and a service ceiling up to 36,100 feet.

Tachikawa Aircraft Edit

In November 1924, Ishikawajima Shipyards (the future IHI Corporation) established a subsidiary company, the Ishikawajima Aircraft Manufacturing Company ( 石川島飛行機製作所 , Ishikawajima Hikōki Seisakushō) . The company's first aircraft was a primary training aircraft called the Red Dragonfly. [ citation needed ]

In 1936, the Imperial Japanese Army acquired a controlling interest in the company, and renamed it the Tachikawa Aircraft Company Ltd. The company manufactured a number of types, mostly training aircraft and fighters for the Imperial Japanese Army. Some were its own designs placed into full production, such as the Ki-9 and Ki-36. A number of others were either short-run specials, or prototypes that did not enter production, such as the Ki-77.

In 1940, the company received license-production rights to the Lockheed Model 14 Super Electra which it produced as the Army Type LO transport. Tachikawa also produced aircraft designed by other Japanese manufacturers.

As with all Japanese manufacturers, production of all types ceased after the surrender of Japan to Allied forces in August 1945. The facilities of Tachikawa Aircraft had been severely damaged by bombing during the war, and most of its property, including its airfield, were seized by the American military and become part of the Tachikawa Air Base. Many of its engineers went to work for Nissan and Toyota, helping develop the technologies of the Japanese automobile industry. The Prince Motor Company (later acquired by Nissan) was a direct spin-out from the former Tachikawa Aircraft Company. [1]

New Tachikawa Aircraft Company Edit

During the occupation of Japan after the end of World War II, all of Japan's aerospace industry was dismantled, designs destroyed and plants converted to other uses. After the ban on aircraft development was lifted in November 1949, Tachikawa Aircraft was reconstituted as the New Tachikawa Aircraft Company Ltd ( 新立川飛行機株式会社 , Shin Tachikawa Kōkūki Kabushiki Kaisha) .


The prototype, fitted with a 450 hp (336 kW) Hitachi Army Type 98 Ha-13 engine, first flew on 20 April 1938. Having outperformed the Mitsubishi Ki-35 in comparative trials, the Ki-36 was designated the Army Type 98 Direct Co-operation Aircraft and ordered into production in November 1938. Production ended in January 1944 after a total of 1,334 Ki-36 had been built (Tachikawa 862 and Kawasaki 472). [1]

The Ki-36 first saw action in China where it saw success. Later, in the Pacific, it proved excessively vulnerable to opposing fighters. It was thereafter redeployed to the safer theater of China. Towards the end of the war, the Ki-36 was employed as a kamikaze aircraft with a bomb of 500-kg (1,102-lb) fitted externally. [2]

Tachikawa Ki-9

In the years leading up to World War 2 (1939-1945), Tachikawa Aircraft Company Ltd of Japan provided the Imperial Japanese Army Air Force (IJAAF) with their Ki-9 single-engine, twin-seat biplane aircraft to serve in the intermediate trainer role. The type served from 1935 until the end of the war in 1945 and some 2,618 were built during that span (220 by Tokyo Gasu Denki / Gasuden into 1945). Reliable and relatively simple to fly and maintain, the Ki-9 excelled in its role, providing the necessary "next step" for Japanese airmen seeking to advance to more complex combat warplanes.

Tachikawa had a Ki-9 prototype readied for 1935 and this aircraft recorded its first-flight on January 7th of that year. A second prototype then followed and mimicked much of what was already established on the first. A third prototype differed by way of the installed Nakajima NZ engine of 112 horsepower (the original two prototypes flew with the Hitachi Ha-13a of 350 horsepower). The down-rated engine was purposeful for the third prototype was to mark the standardized form of a basic trainer (the other two were intermediate types). This basic trainer model was eventually abandoned during development owing to several deficiencies in design.

After testing and formal acceptance by the IJAAF, the Ki-9 entered service in 1935.

The outward design of the Ki-9 was rather straightforward utilizing tried-and-true construction practices. The engine was situated at the extreme front of the fuselage with two open-cockpits over center, the two crew seated in tandem. As a biplane, there was an upper and lower wing assembly, these rounded at their tips and of unequal span. N-type struts and cable bracing were used between the two appendages. The tail unit incorporated a single, rounded vertical fin and low-set horizontal planes. The undercarriage was wheeled at both main legs and a small tailwheel was situated under the rear of the aircraft.

As a training platform, the Ki-9 carried no weapons officially.

There were three production variants of the Ki-9 series. The base Ki-9 was formally recognized by the Army as the "Army Type 95-1 Medium Grade Trainer Model A" and became the initially manufactured form. This aircraft had a length of 26 feet with a wingspan of 34 feet and a height of 10 feet. Empty weight was 2,500lb against an MTOW of 3,500lb. Power was from a Hitachi Ha-13a air-cooled radial piston engine developing 350 horsepower and driving a two-bladed propeller at the nose. Performance included a maximum speed of 150 miles per hour, a cruise speed of 95 miles per hour and a service ceiling of 19,050 feet. The aircraft held an endurance window of some 3.5 hours.

In practice, the Ki-9 was a well-liked machine. The type was useful in allowing students to "fly blind" to get a better handling of their aircraft without complete reliance on the instrument panel or out-of-cockpit-vision. Some models had the rear cockpit faired over with a canopy to serve as a VIP transport serving high-ranking staff members of the IJAAF. Towards the end of the war, when desperation had truly set in for the Japanese, the aircraft was modified for the Kamikaze role and carried a oil-filled drum at the rear cockpit for the suicide mission. During the war, some Ki-9 aircraft fell to the enemy Chinese and were placed back into service under their new owners.

An improved wartime version, with better handling and performance, followed as the Ki-9-ko and this was known officially as the "Army Type 95-1 Medium Grade Trainer Model B". However the definitive standardized production version became the Ki-9-otsu or "Army Type 95-1 Medium Grade Trainer Model C".

Wartime users (beyond the IJAAF) were China-Nanjing, Manchukuo and the Royal Thai Air Force. Post-war users of the Ki-9 became the Indonesian Air Force, the Republic of China Air Force and the Republic of Korea Air Force.

Chiếc nguyên mẫu, trang bị động cơ Hitachi Ha-13 công suất 450 mã lực (336 kW), bay chuyến bay đầu tiên vào ngày 20 tháng 4 năm 1938. Có tính năng bay vượt trội hơn chiếc Mitsubishi Ki-35 trong những thử nghiệm so sánh, chiếc Ki-36 được đặt tên chính thức là Máy bay Trinh sát Hiệp đồng Trực tiếp Kiểu 98 và được đưa vào sản xuất từ tháng 11 năm 1938. Việc sản xuất kết thúc vào tháng 1 năm 1944 sau khi có tổng cộng 1.334 chiếc được chế tạo.

Chiếc Ki-36 được đưa ra hoạt động đầu tiên tại Trung Quốc nơi nó rất thành công. Sau đó, tại Mặt trận Thái Bình Dương, nó tỏ ra rất mong manh trước những chiếc máy bay tiêm kích đối địch, nên được tái bố trí đến các chiến trường an toàn hơn tại Trung Quốc. Cho đến cuối cuộc chiến, chiếc Ki-36 được sử dụng như một máy bay tấn công cảm tử Thần phong (kamikaze) với một trái bom 500 kg (1.102 lb) gắn bên trong.

You've only scratched the surface of Tachikawa family history.

Between 1965 and 2003, in the United States, Tachikawa life expectancy was at its lowest point in 1965, and highest in 2003. The average life expectancy for Tachikawa in 1965 was 37, and 94 in 2003.

An unusually short lifespan might indicate that your Tachikawa ancestors lived in harsh conditions. A short lifespan might also indicate health problems that were once prevalent in your family.

    O prototipo, equipado cun motor de 450 cabalos Hitachi Ha-13, voou por vez primeira o 20 de abril de 1938. Tendo superado ao Mitsubishi Ki-35 en ensaios comparativos, o Ki-36 foi pedido para iniciar a súa produción en novembro de 1938. A fabricación rematou en xaneiro de 1944 despois da construción dun total de 1 334 unidades, 862 por parte de Tachikawa 862 e 472 por Kawasaki. [ 1 ]

    O Ki-36 entrou en acción por vez primeira en China onde tivo éxito. Posteriormente, no Pacífico, demostrou ser excesivamente vulnerable aos cazas inimigos. Despois foi trasladado ao máis seguro teatro chinés. Cara o final da guerra o Ki-36 foi empregado como avión kamikaze cunha bomba de 500 kg instalada no seu exterior. [ 2 ]
