NASA HPR Videos
NASA has published a series of instructional videos on YouTube for those interested in an introduction to high-power rocketry. Links to each of the videos are included here.
Video#1: This video provides a quick overview of high-power rocketry as well as a preview for the rest of the High-Power Rocketry video series. The video describes the two recognized rocketry organizations in the United States and discusses the levels of certification in HPR. Remember, these videos do not replace the guidance of an actual rocketry mentor.
Video#2: This video introduces the basics of HPR and walks the viewer through an example calculation of a rocket’s rail exit velocity.
Video#3: This video introduces various construction materials used in high-power rocketry. It discusses the pros and cons of each material and discusses the bonding methods for each material. The video also includes an introduction on how epoxy works. Please remember that some of these materials are hazardous, so appropriate handling methods should be used and enforced.
Video#4: This video discusses the recovery events that occur in high-power rocketry and the various devices used in safely recovering the rocket. The video includes a discussion of black powder and ejection charge sizing. Remember that black powder is classified as a low explosive, and proper safety measure must be strictly enforced.
Video#5: This video discusses what is classified as a payload and describes the different categories of payloads. The video discusses the use of altimeters and accelerometers in recovery events and different methods for tracking the rocket's location.
Video#6: This video discusses the methods that all rocketeers should use to create a safe and fun rocket environment. As a reminder, these videos are for instructional purposes only and are not meant to replace the advice and assistance of a veteran high-power rocketry mentor.
