Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite
46th AIAA Aerospace Sciences Meeting and Exhibit AIAA 2008-1131 7 – 10 January 20006, Reno, Nevada Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite Stephen A. Whitmore* and Tyson K. Smith† Utah State University, Logan, UT, 84322-4130 A trade study investigating the economics, mass budget, and concept of operations for delivery of a small technology-demonstration satellite to a medium-altitude earth orbit is presented. The mission requires payload deployment at a 19,000 km orbit altitude and an inclination of 55o. Because the payload is a technology demonstrator and not part of an operational mission, launch and deployment costs are a paramount consideration. The payload includes classified technologies; consequently a USA licensed launch system is mandated. A preliminary trade analysis is performed where all available options for FAA-licensed US launch systems are considered. The preliminary trade study selects the Orbital Sciences Minotaur V launch vehicle, derived from the decommissioned Peacekeeper missile system, as the most favorable option for payload delivery. To meet mission objectives the Minotaur V configuration is modified, replacing the baseline 5th stage ATK-37FM motor with the significantly smaller ATK Star 27. The proposed design change enables payload delivery to the required orbit without using a 6th stage kick motor. End-to-end mass budgets are calculated, and a concept of operations is presented. Monte-Carlo simulations are used to characterize the expected accuracy of the final orbit. -

Nasa X-15 Program
5 24,132 6 9 NASA X-15 PROGRAM By: T.D. Barnes - NASA Contractor - 1960s NASA contractors for the X-15 program were Bendix Field Engineering followed by Unitec, Inc. The NASA High Range Tracking stations were located at Ely and Beatty Nevada with main control being at Dryden/Edwards AFB in California. Personnel at the tracking stations consisted of a Station Manager, a Technical Advisor, and field engineers for the Mod-2 Radar, Data Transmission System, Communications, Telemetry, and Plant Maintenance/Generators. NASA had a site monitor at each tracking station to monitor our contractor operations. Though supporting flights of the X-15 was their main objective, they also participated in flights of the XB-70, the three Lifting Bodies, experimental Lunar Landing vehicles, and an occasional A-12/YF-12/SR-71 Blackbird flight. On mission days a NASA van picked up each member of the crew at their residence for the 4:20 a.m. trip to the tracking station 18 miles North of Beatty on the Tonopah Highway. Upon arrival each performed preflight calibrations and setup of their various systems. The liftoff of the B-52, with the X-15 tucked beneath its wing, seldom occurred after 9:00 a.m. due to the heat effect of the Mojave Desert making it difficult for the planes to acquire altitude. At approximately 0800 hours two pilots from Dryden would proceed uprange to evaluate the condition of the dry lake beds in the event of an emergency landing of the X-15 (always buzzing our station on the way up and back). -

During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade. -
Learning from Other People's Mistakes
Learning from Other People’s Mistakes Most satellite mishaps stem from engineering mistakes. To prevent the same errors from being repeated, Aerospace has compiled lessons that the space community should heed. Paul Cheng and Patrick Smith he computer onboard the Clementine spacecraft froze immediately after a thruster was commanded to fire. A “watchdog” algorithm designed to stop “It’s always the simple stuff the thrusters from excessive firing could not execute, and CTlementine’s fuel ran out. !e mission was lost. Based on that kills you…. With all the this incident, engineers working on the Near Earth Asteroid Rendezvous (NEAR) program learned a key lesson: the testing systems, everything watchdog function should be hard-wired in case of a com- puter shutdown. As it happened, NEAR suffered a similar computer crash during which its thrusters fired thousands looked good.” of times, but each firing was instantly cut off by the still- —James Cantrell, main engineer operative watchdog timer. NEAR survived. As this example illustrates, insights from past anoma- for the joint U.S.-Russian Skipper lies are of considerable value to design engineers and other mission, which failed because program stakeholders. Information from failures (and near its solar panels were connected failures) can influence important design decisions and pre- vent the same mistakes from being made over and over. backward (Associated Press, 1996) Contrary to popular belief, satellites seldom fail because of poor workmanship or defective parts. Instead, most failures are caused by simple engineering errors, such as an over- looked requirement, a unit mix-up, or even a typo in a docu- ment. -
1 American Institute of Aeronautics and Astronautics from Air Bubbles Cast in the Fuel (Voids) Can Cause Problems During Hot-Fire Operations
Genetic Algorithm Optimization of a Cost Competitive Hybrid Rocket Booster George Story1 NASA MSFC Huntsville, Al Performance, reliability and cost have always been drivers in the rocket business. Hybrid rockets have been late entries into the launch business due to substantial early development work on liquid rockets and solid rockets. Slowly the technology readiness level of hybrids has been increasing due to various large scale testing and flight tests of hybrid rockets. One remaining issue is the cost of hybrids vs the existing launch propulsion systems. This paper will review the known state-of-the-art hybrid development work to date and incorporate it into a genetic algorithm to optimize the configuration based on various parameters. A cost module will be incorporated to the code based on the weights of the components. The design will be optimized on meeting the performance requirements at the lowest cost. I. Introduction Hybrids, considered part solid and part liquid propulsion system, have been caught in the middle of development goals of the various NASA and military programs. Solid rocket motor technology has matured due to the design simplicity, on-demand operational characteristics and low cost. The reliability of solids, given minimal maintenance requirements, made them the ideal system for military applications. On the other hand, liquid rocket engine technology has matured due to their higher specific impulse (ISP) over solids and variable control thrust capability. Hybrid Rockets have been used in only one flight-production application (Teledyne Ryan AQM-81A ‘Firebolt Supersonic Aerial Target) and one series of recent manned flight demonstrations (Burt Rutan’s SpaceshipOne), suggesting that advantages have been overlooked in some potential applications. -

Bushmaster 25Mm Machine Cannon
7/16/2016 Bushmaster 25mm Machine Cannon LOGIN username PASSWORD password Submit SEARCH Submit BUSHMASTER 25MM MACHINE CANNON By Robert Bruce IMAGE GALLERY Designed in the early 1970’s by engineers at Hughes Helicopters, cannoncaliber BUSHMASTER CHAIN GUNS on the Apache Attack Helicopter, the Bradley Fighting Vehicle, and many other platforms have proven in combat to be without equal in the world. With Hughes having been successively merged with McDonnell Douglas and now Boeing, more than 10,000 of the 30mm M230 and the 25mm M242 are in service in the US and allied nations, enjoying an unsurpassed reputation for reliability, accuracy and operational effectiveness. Concepts Compared Typically, large caliber automatic cannon suffer from any number of problems that must be addressed by tradeoffs in design. Selfpowered guns utilize byproducts from firing the ammunition to operate all functions including feed, locking, extraction, and ejection. This means that their parts must be relatively heavy and resistant to extreme stress. Also, even small variations in the ammunition can lead to stoppages. Gatlingtype weapons utilize external power, usually electric motors or hydraulic systems, to rotate a cluster of barrels into firing position. While this can promote greater reliability and high rates of fire, the penalties tend to be an increase in complexity and maintenance difficulties, a high system weight and bulk, plus a greater cost. In contrast, Hughes engineers offered their single barrel, rotating bolt, electrically driven “Chain Gun,” so called because of its motorcycle type sprocket and chain operating mechanism. Not unlike an automobile engine’s timing chain, the Hughes system provides unparalleled precision, smoothness and positive action to all phases of the cycle of operation. -
