To begin a journey in rocketry and aviation, it's essential to have a solid educational foundation and seek resources that align with your interests. For those studying mechanical engineering, like the original poster, focusing on aerospace-related electives such as compressible flow, combustion, and propulsion is beneficial, as aerospace engineering is a subset of mechanical engineering. Recommended reading includes "Aircraft Design" by Daniel P. Raymer and "Introduction to Flight" by John Anderson, which provides historical context and fundamental principles. Joining local rocketry clubs can offer practical experience and networking opportunities. For younger enthusiasts, engaging with educational games like Kerbal Space Program can enhance understanding of aerospace concepts while making learning enjoyable.
