Hi! Shinden the first(第1回試験飛行), the second(第2回試験飛行) and the third test flight(第3回試験飛行) abstract.
機体状況 : aircraft condition, 成績 : test result, 離陸 : take off, 着陸 : landing, 高度 : altitude(m), 水平飛行 : level flight, 速度 : speed(knot(ノット)), ブースト : engine boost(mmHg), 回転/分 : engine revolution/min, 排温 : engine exhaust gas temperature(°C), 筒温 : engine cylinder temperature, 油温 : oil temperature, 油圧 : oil pressure(atg?), 燃圧 : fuel pressure, メタ圧 : methanol pressure, 対策 : countermeasure, 上昇 : climb 平均翼弦長 : mean aerodynamic chord length (MAC)
The third test flight situation of Shinden.
(1) Change of the nose angle of attack of an airplane by the change in rotation of an engine is nothing.
However, a nose of an airplane falls as engine number of rotations becomes low rotation.
(2) Level flight was possible when the nose of an airplane fell when raising the takeoff flap during level flight by using elevator until raising limit.
