The refined kerosene needs lesser space to make it possible to carry more propellant in the semi cryogenic fuel part. Semi cryogenics is more powerful, ecofriendly and the cost effective compared to cryogenic engines. Key Words: Semi cryogenics, Cryogenics, Propellant, ULV. 1. INTRODUCTION: Kerosene as a fuel has its advantage of burn off gas eco-friendly and cost effective and relative safety. Unlike liquid hydrogen and oxygen which has to store at -253 and 183 degree Celsius respectively, it is stable at room temperature. Kerosene is a fuel which produces line fumes in its paraffin form, it is considered environmentally friendly. It is a non-corrosive fuel, safe to store for a long time. Depending in what kind of container in which it is stored, kerosene can be kept in storage for a 1 year to 10 year. -
Space Launch System (Sls) Motors
Propulsion Products Catalog SPACE LAUNCH SYSTEM (SLS) MOTORS For NASA’s Space Launch System (SLS), Northrop Grumman manufactures the five-segment SLS heavy- lift boosters, the booster separation motors (BSM), and the Launch Abort System’s (LAS) launch abort motor and attitude control motor. The SLS five-segment booster is the largest solid rocket motor ever built for flight. The SLS booster shares some design heritage with flight-proven four-segment space shuttle reusable solid rocket motors (RSRM), but generates 20 percent greater average thrust and 24 percent greater total impulse. While space shuttle RSRM production has ended, sustained booster production for SLS helps provide cost savings and access to reliable material sources. Designed to push the spent RSRMs safely away from the space shuttle, Northrop Grumman BSMs were rigorously qualified for human space flight and successfully used on the last fifteen space shuttle missions. These same motors are a critical part of NASA’s SLS. Four BSMs are installed in the forward frustum of each five-segment booster and four are installed in the aft skirt, for a total of 16 BSMs per launch. The launch abort motor is an integral part of NASA’s LAS. The LAS is designed to safely pull the Orion crew module away from the SLS launch vehicle in the event of an emergency on the launch pad or during ascent. Northrop Grumman is on contract to Lockheed Martin to build the abort motor and attitude control motor—Lockheed is the prime contractor for building the Orion Multi-Purpose Crew Vehicle designed for use on NASA’s SLS. -
The SKYLON Spaceplane
The SKYLON Spaceplane Borg K.⇤ and Matula E.⇤ University of Colorado, Boulder, CO, 80309, USA This report outlines the major technical aspects of the SKYLON spaceplane as a final project for the ASEN 5053 class. The SKYLON spaceplane is designed as a single stage to orbit vehicle capable of lifting 15 mT to LEO from a 5.5 km runway and returning to land at the same location. It is powered by a unique engine design that combines an air- breathing and rocket mode into a single engine. This is achieved through the use of a novel lightweight heat exchanger that has been demonstrated on a reduced scale. The program has received funding from the UK government and ESA to build a full scale prototype of the engine as it’s next step. The project is technically feasible but will need to overcome some manufacturing issues and high start-up costs. This report is not intended for publication or commercial use.

SHUTTLE-C HEAVY-LIFT VEHICLE OF THE 90 ' S Mr. Robert G. Eudy, Manager Shuttle-C Task Team Marshall Space Flight Center ABSTRACT United States current and planned space activities identify the need for increased payload capacity and unmanned flight to complement the existing Shuttle. To meet this challenge the National Aeronautics and Space Administration is defining an unmanned cargo version of the Shuttle that can give the nation early heavy-lift capability. Called Shuttle-C, this unmanned vehicle is a natural, low-cost evolution of the current Space Shuttle that can be flying 100,000 to 170,000 pound payloads by late 1994. At the core of Shuttle-C design philosophy is the principle of evolvement from the United State's Space Transportation System. -

Spaceport Infrastructure Cost Trends
AIAA 2014-4397 SPACE Conferences & Exposition 4-7 August 2014, San Diego, CA AIAA SPACE 2014 Conference and Exposition Spaceport Infrastructure Cost Trends Brian S. Gulliver, PE1, and G. Wayne Finger, PhD, PE2 RS&H, Inc. The total cost of employing a new or revised space launch system is critical to understanding its business potential, analyzing its business case and funding its development. The design, construction and activation of a commercial launch complex or spaceport can represent a significant portion of the non-recurring costs for a new launch system. While the historical cost trends for traditional launch site infrastructure are fairly well understood, significant changes in the approach to commercial launch systems in recent years have required a reevaluation of the cost of ground infrastructure. By understanding the factors which drive these costs, informed decisions can be made early in a program to give the business case the best chance of economic success. The authors have designed several NASA, military, commercial and private launch complexes and supported the evaluation and licensing of commercial aerospaceports. Data from these designs has been used to identify the major factors which, on a broad scale, drive their non-recurring costs. Both vehicle specific and location specific factors play major roles in establishing costs. I. Introduction It is critical for launch vehicle operators and other stakeholders to understand the factors and trends that affect the non-recurring costs of launch site infrastructure. These costs are often an area of concern when planning for the development of a new launch vehicle program as they can represent a significant capital investment that must be recovered over the lifecycle of the program. -
