令和6年能登半島の地震と豪雨による被害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) I wish to express my condolences for the damage caused by the 2024 Noto Peninsula earthquake and torrential rains, and hope for an early recovery. I enjoy DIY as a hobby, repairing and making small and big things.
(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.
