Gear investigation : Banbao LEGO airplane




Running on ground


Motion not too smooth



Completion date: April 30, 2020

Observations
1. Motor to propeller is 24=40=40:24:16.   So propeller is running 1.5 times faster than the motor (24/16=1.5)
2. Motor to wheels is 24=40=40:24. Same speed.
3. The belt can be used to pass on the same speed from one gear to another, and these gears would move in the same direction. The belt can also be used to pass the motion over a longer distance.
4. The axle can be used to pass on the same speed and same direction of the gear on the same axle. Also, the axle can be used to displace the motion to another gear on the same axle.
5. One gear can invoke motions on multiple gears.
6. Gear’s direction can change from left/right motion to become front/back motion by using a direction-changing gear.  While this is happening, the difference in gear sizes can speed up (or slow down) the next set of gear motions.
