History

In may 1944, the Kyushu Aircraft of Japan received an order from the Imperial Navy for a trial manufacture of the 18-shi (experimental) interceptor that became known as J7W1 "Shinden" and Lieutenant M. Tsuruno of NATC (the Naval Aviation Technology Centre) was appointed as a designer in chief.

Higher maneuverability and high speed flying ability were required for this aircraft against heavy bombers was located at thetail, main wings moved to rear and a pair of small horizontal fins called canard lacated on the nose.This distinctive disign resulting from the smaller main wings by the additional lift provided by canard. And without the propella in front, weapons could be lacated at the nose for more efficient attacks.

Following the completion of the first prototype in June 1945, there were theree test flights on 3, 6 and 8 August 1945 and recorded a total of 45 minute flight; however the war was over in the following days and the Shinden did not see any actual battle.

A propeller was struck in the ground the moment it thought that the nose was a little raised though it was the airplane which began gliding.
The engine is stopped, and it is being checked.
The propeller whose tip curved about 30cm. The side wing breaks a little, too.

Prototype "SHINDEN" flying record

Mushiroda Aairport Hukuoka-city Hukuoka-pref. JAPAN

<1st test flying> in 3ed Augst 1945

Body conditions

-14% ofcenter of gravity position : (It faces an average wing string head.)

main wing Flap : 20°

front wing flap : 26°

Record

A raising rudder is taken with takeoff 100 kt in the above conditions, takeoff with speed 105 kt.
Takeoff operation is easy

The right inclination by the propeller torque is very much made high. It can't be modified by the Amendment.

altitude 400m (level flight).   .

the right inclination by the propeller torque

Landing : gliding speed 130 kt

Landing operation is difficult due to the inclination by the propeller torque

<2nd test flying> in 6th Augst 1945

Body conditions

It is the same as the first flight

Record

The nose falls down though it was amended in the top during the rise.

A body leans to the right though it was amended in full left. The rudder is put, and it is high.

It was full lowered, and it landed with the rudder because the nose was raised suddenly when a rudder was a little raised to the top just before the landing.

Countermeasure

A sleeve is set up in the oil cooler.

<3ed test flying> in 8th Augst 1945

Body conditions

It is the same as the first flight

Record

The nose falls down as it becomes low rotation though there is no change in the nose due to the increase and decrease of the engine rotation specially. Altitude 400m

It can fly horizontally if the nose falls down and a rudder is raised if a fulap is full raised during the level flight.

Countermeasure

Bigger sleeve is set up in the oil cooler

Main wing falp 30°

Front wing flap is changed to 3°
