Launch vehicles, satellites

Aeronautics is the science of atmospheric flight. Aviation is the design, development, production, and operation of flight vehicles. Aerospace engineering extends these fields to space vehicles. Transonic airliners, airships, space launch vehicles, satellites, helicopters, interplanetary probes, and fighter planes are all applications of aerospace engineering. 

Secondary (and high-rate primary) batteries were specially developed for the US Space Administration (NASA) Apollo ILM Saturn programme. A total of 24 secondary and primary silvcr-zinc batteries were used on each Saturn V vehicle. The Moon Buggy or Lunar Rover used for driving on the surface of the moon in 1971 was powered by two manually activated secondary silver-zinc batteries. This vehicle reached speeds of 5-6 miles/h. The Agena, a workhorse launch vehicle/satellite since 1959, is powered with silver—zinc batteries. When originally developed, in 1959, these batteries had a power density of 36 W h/kg. This has since been increased to 53 W h/kg. 

Miscellaneous Niobium also finds use in satellite launch vehicles and spacecraft and one of the principal applications for niobium-base alloys is in the production of super-conducting devices. 

An example of propellant tailoring is the fuel used to launch the first U. S. satellite into orbit. The original fuel for the launch vehicle was ethyl alcohol. MAF-4 (also known as hydyne or U-DETA), a mixture of 60% UDMH and 40% diethylenetriamine (DETA), was formulated to simulate the physical properties of C2H5OH but provide the increased propellant performance (using liquid oxyen as the oxidizer) requirements of the mission. 

Polar Satellite Launch Vehicle (PSLV) For launching IRS/Sun-Synchronous Orbit (SSO) Satellites. India launched its first unmanned spacecraft under its mission Chandrayaan- to explore the moon on October 22, 2008 with the help of upgraded version of PSLV (also called PSLV-XL). 

Geo-synchronous Satellite Launch Vehicle (GSLV) For creating links among remotest and most inaccessible parts of the country. Also, it makes it possible to keep a close watch on our weather, climate and pollution.

India s four-stage Satellite Launch Vehicle-3 (SLV-3) which put the Rohini Satellite in orbit on July 18, 1980 used a composite propellant based on terpolymer of butadiene-acrylic acid-acrylonitrile (PBAN) for the first and second stage motors whereas LTPB-based composite propellant was used for the third and fourth stage motors [6]. 

ISRO polyol is considered to be a substitute for HTPB binder and propellants based on it are used in sounding rockets (RH-300). Such propellants are also considered as candidate propellants [94] for the booster stages of Polar Satellite Launch Vehicle (PSLV). The easy availability of castor oil coupled with its low cost makes ISRO polyol more attractive compared with current binders [95] like PBAN, CTPB and HTPB. 

However, its application for bulk manufacture of composite propellants for missiles or satellite launch vehicles is not reported in the literature. 

Delta-ll rocket—launch vehicle commonly used by NASA and the military to put satellites and probes into space. 

Although the Soviet Union/Russia launched the first satellite into space in 1957 and has made more than 2800 launches since that time, liquid hydrogen was very rarely used except for the Energia launch vehicle developed for their Buran Space Shuttle. After the only successful launch of an unmaimed Buran orbiter in 1988 using the Energia rocket, this program was canceled due to lack of funds.

Components of the Physical Process The Lockheed Martin Astronautics (LMA) Titan rv B is a heavy-lift space launch vehicle used to carry government payloads such as Defense Support Program, Milstar, and National Reconnaissance Office satellites into space. It can carry up to 47,800 pounds into low-earth orbit and up to... 

Reliable communication to and from a satellite requires a knowledge of its position and velocity relative to a location on the Earth. Details of the relevant astrodynamics formulas for satellite orbits are given in Griffin and French (1991) and Morgan and Gordon (1989). Launch vehicles needed to deliver the satellites to their intended orbits are described in Isakowitz (1994). 

The design for a constellation of satellites to serve communications needs, includes choices for the number of satellites, their orbital parameters, the satellite G/T and EIRP, etc. These mission analysis and design topics involve trades of many factors such as total communications capacity, link margins, space segment and Earth segment costs, reliability, interconnectivity, availability and cost of launch vehicles, mission lifetime, and system operations (Wertz and Larson, 1991). 

The software for the EADS Satellite Launch Vehicle contains 100,000 lines of mission-critical software. The software is written in Ada and is checked for runtime errors using the Polyspace static analysis tool. Two types of error are detected certain errors and possible errors.
