This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless igniter system (namely WISys in this research) is a modern type igniter system, which utilizes the concept of radio frequency (RF) communication between a transmitting device and a receiving device and also the usage of a specified designated igniter. This type of igniter system is now becoming the main focus in most rocketry industries, especially for small scale solid rocket motor (SRM). The main purpose of using a wireless igniter system is because it can provide secure feeling when conducting experiment and testing, especially when it comes to the matter of explosive materials. The main components that a wireless igniter system must have include a transmitter, a receiver and an igniter. In this research, both the transmitter and receiver were designed to be function able at various ranges and the maximum communication range must reach up to 100 meters. Therefore, selection for wireless communication module is very significant and here the XBee-S1 Starter Kit from Cytron Technologies was used as the main wireless communication module. With its ability to communicate with another XBee-S1 Starter Kit as far as 100 meters range and simplicity of performing configuration and synchronisation, the XBee-S1 Starter Kit module is simply the best choice, especially for those who are unfamiliar with radio frequency communication. Moreover, the power supply for the ignition must be at least 12V so that there is sufficient heating energy to ignite the pyrolant contained inside the igniter within 3 to 5 seconds. For a good igniter, the igniter must possess good characteristics, such as made from stainless steel, sustainable material, high melting point, able to withstand very high pressure and temperature, high resistance to rust, small size and portable, light weight and tough. So, igniter with these characteristics will be able to store enough pressure inside the combustion or primary chamber to achieve complete combustion of the pyrolant before it is forced out from the igniter into the thrust chamber of rocket motor to burn the propellant grains. As a conclusion, with high pressure inside the primary chamber the velocity inside the chamber would be low. Hence, the burning rate of the pyrolant would also be slower. With this condition achieved, the pyrolant inside the igniter could be burnt completely.

Download or read book Solid propellant Rocket Ignition Systems Ii a Research Program for the Scientific Design of Igniters written by CHARLES F. SHARN and published by . This book was released on 1961 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical program for the design of solid-rocket igniters is developed from an evaluation of rocket-ignition processes. The evaluation consists of: the derivation of igniion fundamentals from an analysis of combustion-ignition theory; the determination of rocket-ignition principles from an analysis of the important processes involved; and the development of anANALYTICAL, ROCKET-IGNITION MODEL TO DESCRIBE THE FUNCTION OF THE IGNITER IN THE IGNITION PROCESS. Based on the rocket-ignition model an engineering-type research program is constructed for the study of ignition in four basic phases: (1) the ignition system, (2) ignitability, (3) hydrodynamic phenomena, and (4) rocket ignition. The plan is to develop quantitative and qualittive ignier-design criteria through experimental and theoretical studies of each phase and the interrelations among the phases. (Author).

This book was released on 1967 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: A digital computer analog model of a solid propellant rocket motor and performance evaluation system was developed. Heat and mass balance effects of the igniter, propellant, and insulation during ignition and chamber filling were modeled. Results include investigation of flame spreading, ignition criteria, and contribution by insulation to motor performance. Comparisons of predictions and experimental tests are included. An IBM model 7094 computer was used for the analysis. The FORTRAN computer program is included. (Author).

Book excerpt: BION [Believe It Or Not], Book #3 of the CUL8R Time Travel Mystery/Romance series. Change the past, Save the future. Four high school friends are able to do two things no one else on the planet can do . . . talk with dead people and time travel to the past. However, Kelly, who lost her phone during their last adventure, is temporarily grounded. She worries that her new friends will time travel without her, leaving her all alone in her new home in Ft. Myers Beach, Florida. But they surprise her on her birthday and soon they are back in Scott’s lab, listening to the old radio that Thomas Edison had invented and called “The Telephone to the Dead”. As they slowly turn the dial Kelly, Scott, Austin and Zoey hear hundreds of sad, lonely voices of souls that have passed but apparently never moved on, pleading for help. When they first discovered the radio in Kelly’s aunt’s garage, they had been touched by the cries and pleas coming from its speakers, but they had no way to go back in time to help them. That is, until Scott reveals an invention of his own . . . a time travel app. They’ve already tested it twice, with both trips being very successful, but not without danger. Even though they returned with a few scrapes and bruises, and even a gunshot wound, they are eager to go on a new adventure and help solve a mystery. A young woman’s voice comes through and asks them to find her twin brother, Jesse, who had run away to the circus in 1927, then disappeared and was never heard from again. Going back and living with a circus sounds like fun. Plus an old book written by his sister provides a glimpse into the past . . . as well as a photo of Jesse, a photo that grabs their attention and sets the girls' hearts racing. They land in a cornfield in Wichita Falls, Texas as the circus is setting up. It doesn’t take them long to discover that circus life is not all glamour and fun; it’s a lot of hard work. As usual, they jump in and quickly find jobs, places to sleep and new friends. But most importantly, they find Jesse. Now all they have to do is keep him alive. For Zoey and Jesse, it’s love at first sight. It’s a first romance for both of them and their love blossoms as they travel from city to city. Zoey knows she’s too young to settle down and that Jesse is from a different time and culture, but her feelings for him are strong. Her and her friends’ time travel mission has taken on a new dimension. Should they be successful and save his life, will Zoey be able to let him go? Is it possible for him to come to 2013 with her? Is it possible for her to stay in 1927 with him? Ultimately, can she give up everything she has in the present for true love in the past? Jesse’s talent working with the big cats catches the attention of the Martin Maxwell, the owner of the circus. Maxwell promotes him to the center ring as a replacement for their current lion tamer who is planning on moving up to the Ringling and Barnum & Bailey Circus. Unfortunately, not everyone shares Zoey’s love for Jesse and wants him to disappear forever. Kelly, Scott, Austin and Zoey must figure out who wants Jesse dead and stop him or her before Jesse’s fate is sealed.
