Instarocket is an educational tool for you to learn about sizing earth-to-orbit launch vehicles. Instarocket is developed by Zero Point Frontiers Corp. (ZPFC), an engineering firm with expertise in design integration, system analysis, architecture development, and decision management. We provide payload and subsystem analysis and integration support of large-scale space flight systems composed of inter-dependent vehicles, systems and infrastructure for government and commercial customers. Instarocket is our first attempt to translate some of the techniques and expertise that we use when working with NASA and the aerospace industry into an educational tool that can help others understand more about engineering, design, and propulsion systems. We will continue to refine this product, and create additional products for iPad, iPhone, and Mac, that will support this outreach. And, if you like what you see, and would like to procure our services, please contact us at www.zeropointfrontiers.com. When designing a launch vehicle, the first step is sizing the stages to get a desired amount of payload into orbit. This tool will help you learn about how sizing of a launch vehicle works, as well as how rockets work. The included extensive help files will walk you through the basics of orbits, rocket propulsion, delta-v, delta-v goals and delta-v penalties. The language is casual and intended for people new to launch vehicles. Equations are included for better understanding of the concepts. Features: Simple diagram showing launch vehicle layout Diagram shows volume of fuel vs oxidizer User-controlled sliders for stage propellant loads User-controlled slider for payload mass Dynamic updates for all outputs Email configuration information from within the app Extensive help file: Descriptions of all terminology Introduction material for how rockets work Support for AirPrint from help files Inputs: Vehicle diameter Interstage and shroud masses Stage PMF, number of engines, fuel type Engine Isp, thrust, and length Outputs: Mass breakdowns Delta-v for each stage Delta-v bonus/penalty for each stage Total delta-v Delta-v margin for orbit insertion
