Week 8: The V-2

---

By World War II, rocketry had gone from Goddard's backyard experiments to a full industrial weapons program — with everything we've covered so far about thrust, drag, gravity, and stability now applied at a terrifying scale.

History

Nazi Germany's V-2 program represented the biggest leap in rocketry since Goddard. It was the first rocket to reach the edge of space and the first to be guided rather than simply aimed and fired ballistically, using an onboard system to correct its path mid-flight.

Forces

This week introduces guided flight and trajectory. Unlike the unguided rockets we've discussed so far, the V-2 could adjust its course during flight instead of relying entirely on how it was aimed at launch.

Math

R = v²·sin(2θ)/g (simple parabolic range, ignoring drag and guidance)

Worked example (metric): launched at v = 100 m/s at a 45° angle: R = 100² × sin(90°) / 9.81 = 10,000 × 1 / 9.81 ≈ 1,019 m.

Advances

The V-2 program was led by Wernher von Braun and his team — many of whom would later go on to lead the American space program after the war.

Key Date

The first successful V-2 launch took place on 3 October 1942.

Safety Note

Wartime rocketry had no concept of civilian range safety. NAR launches are the opposite: spectators are always kept behind a defined minimum distance line, a rule with no equivalent in this week's history.
