During World War II, it was found that there was a video recording and design material of a research aircraft called "Kenzo" which was secretly developed to become the world's fastest airplane. Experts pointed out that "what remains is a miracle, a valuable discovery that shows the state of development at that time."

`` Kenzo '' is a research aircraft that was developed during World War II with the aim of setting a world record of airplane speed, a propeller aircraft that has not been broken at 699.9 km / h in December 1943 Recorded the highest speed in Japan.

The development proceeded in secret and no relevant data had been identified so far, but it was found that the National Science Museum had video and design documentation.

When the `` Gifu Kagamigawa Air and Space Museum '' etc. in Gifu Prefecture proceeded with the investigation, the video turned out to be the one when the highest speed in Japan was recorded, and the pilot landed from where `` Kenzo '' took off and the pilot It is recorded for about five and a half minutes before getting off.

In addition, there were about 200 materials related to design, records of enormous calculations and experiments were left, and specifications were found that indicated that there was a plan to install a jet engine to increase speed further .

Mr. Tsuyoshi Mizuno of Gifu Kagamigawa Air and Space Museum said, “Research materials during the war will be incinerated, so the remaining thing is like a miracle. The materials are filled with a huge amount of calculations It is a valuable discovery that shows the state of development at the time. "

These materials will be on display at the Gifu Kakagamihara Air and Space Museum from 8th of this month.

Run-take-take-fly-land "impressed by the image"

According to the Gifu Kakagamihara Air and Space Museum, the video found this time shows that `` Kenzo '' recorded 699.9 km / h at the current airfield in Kakamigahara City, Gifu Prefecture, a flight on December 27, 1943 Was recorded.

The aircraft recorded in the video had features such as being painted to reduce air resistance and being fitted with a canopy covering the cockpit, indicating that the shooting date could be identified.

The footage is about five and a half minutes, and shows that the engine is turned on, the propellers are turned, then the airplane takes off while accelerating the runway, flying in the sky, and landing and the pilot descending.

Mr. Mizuno of the museum said, "I was impressed by seeing the video. It is obvious that the landing is fast, and I think that what remains in the video is really amazing."

“Fast” competition Overheating in each country

Kenzo is an army research aircraft developed during World War II by the Aviation Research Institute of Tokyo Imperial University, etc., aiming for a world record of airplane speed.

Development began in 1938, just before the Pacific War, and the aircraft was completed and flight tests were repeated in 1947.

The speed was improved and improved at each test, and on December 27, 1943, it recorded 699.9 km in the 31st test.

According to the Gifu Kagamigawa Air and Space Museum, the development of high-speed airplanes was heating up mainly in Europe, and propeller planes exceeding 700 km / h had already been made in Italy and Germany.

The development of `` Kenzo '' was pursued to update the world record of speed, and the materials found this time also revealed that the design of the next aircraft equipped with a jet engine was underway .

However, the development of the next aircraft did not materialize due to the deterioration of the war situation, and Kenzo was destroyed by the U.S. forces after the war.
