A NEW APPROACH TO PROPULSION SYSTEM DEVELOPMENT, BRAZILIAN STYLE

SUMMARY

This is the story of a volunteer-based program, that used rocket propulsion system development as a tool to introduce students to the engineering world;

This presentation describes how it all started and developed over the years, the challenges faced and the solutions found to keep the organization alive and doing what it was designed for.

INTRODUCTION

The idea came from an article describing countries with similar educational level, but with large differences in technological capabilities.

Example: Chile and South Korea.

That difference resulted from the quality of the opportunities given to students to apply, on their professional life, the knowledge acquired at school.

METHODOLOGY

Challenge Based Training:

Difficult enough to call the students attention, and,

Feasible, in order to keep them interested in accomplishing the mission.

Liquid rocket engine based propulsion system

would meet these requirements.4


HOW TO MOTIVATE THE PARTICIPANTS

Create a stimulant and enthusiastic environment;

Highlight the application of the students background knowledge;

Establish specific targets to be met;

Match the program schedule to the students timing;

Create a legacy for the next group.

LESSONS LEARNED

Winning team characteristics

Ability to nominate a leader;

Team work skills and ability to share knowledge;

Committed to success;

Time devoted to the Program;

Drafting skills, hand made drafts;

Computer literacy: spreadsheet, 3D drawing.10

Team Assignment: the 5 kN engine


LESSONS LEARNED

Cash is king: as the quantity and complexity of the project increases, the need for funding follows suit;

Ground testing: finding a suitable location to test the products was not completely successful;

Symposiums: an opportunity for the students to share their recently acquired skills with their peers.

LESSONS LEARNED

A real life application help increasing the morale of the team;

Its nice to work with funding available before the program starts.

As the news spreads among the students, there are new universities interested in joining the Program.

WHAT’S NEXT ?

This program has grown beyond any expectation, and its expansion is currently being limited by our ability to manage it.

The time has come to build a flight vehicle;

Tests benches are desperately needed ;

We have yet to explore the world of propellant tanks, valves and flight control computers;

Our crystal ball shows a 20 kN engine in the future.

21


CONCLUSION

We would like to go even further with our Challenge Based Training, aiming for space, or as we say in Portuguese, “Rumo ao Espaço”.
