Water Powered Rockets

Dr Mark W. Johnson

Propelling students to greater heights

2EE2006 Liverpool: 25th July 2006

Introduction

Project for about 100 Year 1 Mechanical Engineering students.

Two separate weeks mid December and late January.

Objective to improve understanding of engineering science learnt in previous 3

months and to develop team working and communication skills.

Students working in groups of 5 with self organisation.

3EE2006 Liverpool: 25th July 2006

Objectives

1) To design and build a water propelled rocket and launcher using the materials provided.2) To predict the rocket performance (apogee height) using Year 1 engineering science.3) To test the rocket and compare the measured and predicted apogee heights.

Week 1
