令和6年能登半島地震の御見舞と早い復興を願います。 私は趣味としてDIYを楽しんでいて小さな物から大きな物まで修理したり作成したりしています。 (写真:梅津正道隊員撮影)We would like to express our condolences to the Noto Peninsula Earthquake of 2020 and wish for a speedy recovery. I enjoy DIY as a hobby, repairing and creating things from small to large items. (Photo: Photographed by Masamichi Umezu)
(2013-2022) I will be working as a maintenance instructor at an aviation vocational school in Sakai City, Osaka Prefecture. I taught what I learned 30 years ago, but what I learned when I was young surprisingly stayed in my head. I will retire in 2022 at the age of 65. I served for 9 years.
The school’s classes mainly taught electrical work and avionics and electricity. Since I love DIY, I have created various teaching materials to use in class. There is no English translation below, but please take a look at the photos and enjoy.
A propeller governor is a device that converts the movement of flyweights into the movement of a hydraulic pilot valve, sending hydraulic pressure to the propeller and removing the sent hydraulic pressure. Hydraulic pressure is used to change the pitch of the propeller.
The reason for changing the pitch of the propeller is to keep the propeller’s rotational speed (= engine rotation) constant and maintain good propeller efficiency at all times. The role of the governor (flyweight) is the rotation speed sensor. It is used in many places other than propellers, and its name changes depending on the location, such as 〇〇governor.
