An Illustrated How-To Guide to High-Power Rocketry
By Mark Canepa
Here is a quick glance through a few of the subjects covered in each chapter of Modern High-Power Rocketry 2
CHAPTER EIGHT: HIGH-POWER ELECTRONICS
This chapter will introduce you to all of the basics of high-power electronics. What is the most common type of electronic device used in high power? What is the difference between an altimeter and a timer? Are all altimeters the same? What is Mach and how does it affect some altimeters? What do altimeters and timers cost and where can I find one? How do I hook up my ejection charges to the altimeter? What are the most common causes of errors with altimeters and other on-board electronics--and how do I prevent them? What is a static port and how is its size calculated? Is a static port the same thing as a vent hole? What is a beeper? Are there GPS units used in high-power rocketry? This chapter contains dozens of new photogrpahs and discusses the latest in high-power electronics.
CHAPTER NINE: ALTIMETER BAYS
This brand new chapter covers the basics of altimeter bays in high-power rocketry and shows the reader how to build seven different bays. The chapter covers the fundamentals of a good bay design and answers the important questions that every rocketeer faces when building his or her own altimeter bay: Why must the altimeter bay in my rocket be kept isolated from the ejection charges? Where should my altimeter bay be placed in the rocket? Can the altimeter bay be removable? What method can be used to arm the altimeter once it is in the bay? Can I buy an altimeter bay that is altready assembled? Can I move one bay from one rocket to another? How do I cut a hatch in my rocket's airframe for a hatch-accessed bay? What types of switches are used in altimeter bays? This chapter contains diagrams and photogrpahs that will make it easy for the rocketeer to construct their own buy--or find one from one of the major manufacturers.
CHAPTER TEN: DEPLOYMENT AND RECOVERY
Did you know that recovery problems are the number one cause of mishaps and crashes in high-power rocketry? The Up part of rocketry is easy--the real challenge rests with getting your rocket back safely. This chapter will help you prevent errors in your recovery system. Entirely rewritten and photogrpahed, Chapter Ten goes through all of the common causes for deployment failure and will help you attain Level One through Level Three certification. With diagrams and photos illustrating both dual and single deployment, this chapter also covers the following issues: What are the advantages of dual deployment and how does it work? What is a recovery harness an how long should it be? What should the harness be made of? how do successful rocketeers attach their harness to the rocket? What is the best descent rate for a high-power rocket and where can I find a descent rate calculator for free? How do I pack my parachute? What are shear pins and how do they work? This chapter has it covered, and much, much more.
CHAPTER ELEVEN: BUILDING
THE LEVEL ONE ROCKET
Once again, Modern HIgh-Power Rocketry uses a Loc HiTech 45 as a platform to demonstrate the basics of building an entry level high-power rocket. But this time an enitely new rocket is built and you will follow it from kit form, to launch, and to the suprising CATO on the pad for its very first flight! This chapter covers all of the basic construction techniques: What epoxy to use and why. Replacing the open eyebolt with a closed bolt. How to install postive motor retention. How to attach the parachute, launch lugs, and much more (including how to repair a damaged rocket). In addition, this chapter is one of several chapters in Modern High-Power Rocketry 2 containing Case History studies from rocketeers who describe their own experience in reaching Level One certification with either NAR or Tripoli.
