ICAO's ACN-PCN Method and Aircraft-Pavement Interaction
Multi-wheel gear assemblies of future aircraft are not compatible with pavements rated in the ACN-PCN system given by the International Civil Aviation Organization (ICAO). The Aircraft...
Reliability-Based Analysis and Design of Flexible Airfield Pavements
This paper illustrates, a new reliability-based procedure to analyze existing pavements and design new pavements that is being developed by the U.S. Air Force. The procedure uses a rigorous...
Pavement Design Considerations for Heavy Aircraft Loading at BAA Airports
BAA operates seven airports in the United Kingdom. Two of them, Heathrow and Gatwick, handled 61 million passengers in 1991 with 543,000 air transport movements, 25% by wide-bodied aircraft....
Evaluation of a Large Aggregate Asphaltic Layer in an Airside Pavement
A new analytical method of designing large aggregate asphalt mixes (LAM) was used to design a thick asphalt base layer for an aircraft taxiway. The results of an analysis on the material...
Evaluation of Runway Roughness for Fighter Jets
A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to...
Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...
Measurement and Analysis of Airside Pavement Roughness at the Dallas/Fort Worth International Airport
In May 1990, Dallas/Fort Worth International Airport management contracted with Harding Lawson Associates to implement a pavement management system for that airport. In this implementation,...
Use of Surface Treatments on Airport Pavements
Asphalt is generally used as the surfacing for flexible airport pavements with airline passenger jet aircraft. In Australia and its neighbouring territories, surface treatments (seals)...
Planning for Airport APM Systems—New Applications
Traditionally, automated people mover (APM) systems at airports have been used to move passengers between a main terminal, in which ticketing and baggage claim occurs, and aircraft gates...
APMs at Tampa International Airport—A Story of Innovation
The Tampa International Airport has been at the forefront of integrating Automated People Movers into airport design for more than twenty years. The need for APM technology comes from...
Lumped Mass Modelling for the Dynamic Analysis of Aircraft Structures
Heavy Aircraft Damage to Rigid Airport Pavements
A theoretical solution is presented for the damage caused by heavy aircraft at the transverse joints in a rigid airport pavement. Large stresses in the subgrade generate significant permanent...

Inflation Concept Development for Inflatable Lunar Structures
Inflatable structures require mechanical equipment to initiate and maintain inflation. Several inflatable structural shapes and forms have been proposed by a number of different authors....
The Small Mars Rover
Mars rover is one of the principal technical means intended for studying the surface of Mars. The first Mars rover was delivered to the Mars surface in 1971 and was designed for studying...
Experimental Study of Underground Exploration by Auger Boring on a Mars Rover
A system study was conducted on the possibility of exploring Mars using a Mars Rover, and particular efforts were focused on the underground exploration of Mars by an auger boring machine....
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....
On-Orbit Assembly and Refurbishment of Lunar Transfer Vehicles
Initial flights of space-based manned lunar transfer vehicles (LTV) will require some on-orbit assembly and checkout due to mass and volume limitations of the Earth-to-orbit (ETO) launcher....
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...
Back to the Future: A Saturn V-Based Low Earth Orbital Transportation Node
The Space Exploration Initiative requires a heavy-lift launch vehicle to succeed. Reviving the Saturn V represents the best option for regaining heavy-lift. Utilizing the Saturn V's two-stage-to-orbit...
