The behavior of unsurfaced runways under aircraft movement has been studied for a number of decades. A good number of the design nomograms developed have been intended for the prediction of runway performance in a variety of soils and under diverse loading conditions. At the same time, a comparison of the design values with the actual behavior of the runways in the field, indicates a very large scatter of the results.

Aircraft operations on soft fields are limited due to field rutting. Each subsequent aircraft pass, defined as one takeoff and one landing, increases field rutting until the field reaches a point where further aircraft operations are no longer permissible. The ability of aircraft to operate on soft fields is often expressed as a function of aircraft landing weight and the California Bearing Ratio (CBR) of the field, which measures the ability the soil to resist compressive loads. Because soft...

Vertical Take-Off and Landing (VTOL) has primarily seen research and development in the two traditional fields, namely the rotary wing and jet propulsion, with each seeking incremental improvements in thrust generation and fuel efficiency, respectively. In recent years, there has been increasing interest in the viability of the Cross-Flow Fans (CFF) being the primary source of aircraft propulsion. There has been measured success in horizontal flight; however, VTOL propulsion with CFFs remains...

The allocation of runway slots at the high-density airports by means of an auction is studied. Previous approaches to slot auctions have not allowed for the interdependency of slot values to the air carriers--a single slot for a landing of an aircraft is likely to be of little value without a corresponding slot for a subsequent take-off of that aircraft. A Slot Exchange Auction is designed, its theoretical properties and practical implementation discussed. It is shown to allow the slot market...

The criteria for landing zones (LZs) and drop zones (DZs), also known as austere entry surfaces, are extensive and varied. They range from very specific guidance on required geometry to more general guidance on required bearing strength of unprepared surfaces, such as soil or ice, and the smoothness of those surfaces. Current practice for siting LZs and DZs includes site surveys by trained personnel, often in hostile environments. Additionally, with the continued advancement of image analysis,...

As the state of the art advances, the helicopter becomes more complex with accompanying difficulties in the development cycle. Also, the customer organizations become larger, more efficient, demand more reliability and accuracy, and in general, refine their capability in all areas. The manufacturers and government in turn are forced to provide more comprehensive and accurate information about the product, thus requiring an ever increasing flight test effort. This handbook discusses flight...

The purpose of the present work was to qualitatively and quantitatively model the air wake created by an aircraft carrier flight deck and superstructure in order to understand how it affects aircraft on approach and landing. The burble effect is the name given by navy pilots to the velocity deficit and downwash field immediately aft of an aircraft carrier. This turbulent region of air has adverse effects on landing aircraft and can cause pilots to bolter, missing the arresting wires and...

An analysis has been developed to model a rotorcraft with power loss. Partial power recovery to a flyaway condition, partial power landing, and autorotation to landing with a complete power loss are considered. An optimal control procedure is implemented to predict the pilot response to the power loss with the objective of minimizing the horizontal and vertical impact velocities in the case of a landing and achieving a sustainable steady state flight condition for flyaway. The physical and...
