A Novel Aerobrake Design for a Mars Lander
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....
Structural Considerations in the Design of a Mars Mission Aerobrake
A new area of civil engineering is emerging. This area will provide structures for outposts on the moon, resource development and exploration of Space. Spacecraft traveling at very high...
Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...
Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...
A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...
Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...
The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...
An Operational Evaluation Process for Long-Duration Mission Habitats in Space
In preparation for long-duration manned spaceflight into the 21st Century, the ergonomical and psychological aspects of space habitat architectures are being investigated in Europe. Used...
LIAC: A Closed Ecosystem Research Facility
A preliminary design for a closed research facility capable of supporting multispecies and ecosystem level experiments is presented. This project will support NASA's Controlled Ecological...
SALSA: A Lunar Submillimeter-Wavelength Array
A conceptual design is described for a lunar submillimeter-wavelength interferometer called SALSA, a Synthesis Array for Lunar Submillimeter Astronomy. The intent is to describe SALSA...
Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...
Preliminary Investigation of a Lunar 16 Meter Optical Telescope
The results of a year-long effort to develop a design concept for the structure of a 16 meter lunar optical telescope are presented. Various mounting configurations and mirror configurations...
Object Oriented Spacecraft Architecture
This paper describes an architecture for simplifying the spacecraft design and maintenance process: Object Oriented Spacecraft Architecture. Like object oriented programming, the strategy...
Internal Pressure in a Lunar Inflatable Structure
Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. A critical design factor is the internal atmospheric pressure necessary...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
Minneapolis/St. Paul International (MSP) Part 150 Implementation Design Overview
In February 1991, Matropolitan Airports Commission (MAC) selected the consulting team of Aviation Planning Inc., Wyle LAboratories Inc. and the Center for Energy and the Urban Environment...
Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...
An Economic Evaluation of the Thunder Bay Air Terminal Development Strategies
The Air Terminal Building (ATB) at the airport in Thunder Bay, Ontario, Canada is currently being utilized at approximately 140% of its design capacity. In response, three alternative...
Management of Design
Denver's new airport uses the services of over 80 separate design firms. The existing airport, Stapleton, could not be expanded to meet the forecasted demand of 1,200,000 operations with...
