The Hineri-komi (捻り込み—literal meaning: twist inside) was an air combat maneuver widely used by fighter pilots of Imperial Japanese Navy Air Service (IJNAS) through the Second Sino-Japanese War and the Pacific War.
The Hineri-komi maneuver was invented and developed by Isamu Mochizuki in the early 1930s during his four-year stay with Yokosuka Air Group.
Minoru Genda, who was also part of Yokosuka Air Group at the same time, observed this technique during the training sessions with Mochizuki and helped to formalize it in order to be widely adopted by other IJNAS pilots in dogfights.
The maneuver starts with a steep climb into a half loop, where the pilot applies (e.g., right) rudder to yaw his aircraft and performs a side slip.
After the resulting twisting motion, the pilot uses elevator to pull the aircraft up, which brings it into a horizontal flight in the same direction as the loop began.
