launch a rocket

We made hybrid rocket, and we perform a launching experiment of the rocket and check the performance.
The hybrid rocket is different from the conventional rocket.
It does not use the gunpowder, therefore low-cost, and superior in safety.
Drew a drawing with a Solidworks in producing the rocket, and confirm whether a material does not have deficiency.
We perform a strength calculation on a breaking test necessary for launching every part of a material and the body to use before launching.
We confirm that the big difference and strength calculation of weight and the center of gravity with the body which we made do not have any problem by classifying weight into a material
We made approximately all an engine and the body of the launching body, a deployment instrument in an own group in this year and tested launching in Izu Oshima.
As a result, we recorded altitude of the launching altitude all-time record third of the student.
