stopped motions and comments about Wakusei-Shibamoto-10go(P-Shiba-10)


1
launch

Thrust water flow from launch pad can be seen.
water: 800 ml.
tank capacity : 1500 ml.
pumping about 20 times (I think it is 3-4kg/cm2.)
The man who is launching is me.
naked foot because of wetting.
2
Main tank is horizontal.
It cause the nozzle without water.
So, the maintank's direction is looking downword.
The speed is faster than 1st photo, so sharpness is lost.
3
The white stripe is a tape measure 2 meters length.
I think it is 8 shots/second.
The car runs 2 meters between 0.250 sec to 0.375 sec,
then mean speed is between 5.3 m/sec to 8.0 m/sec, 19.2 km/h to 28.8 km/h.
4
The car is out of vision, but thrust is going.
The top speed is more than 20 km/h.
And, the pressure is not so high, I will be able to make the car higher speed.
