The entire TAC study is briefly summarized for background information. The, most important research items for the areas of noise, congestion, and emissions are identified. Other key research areas are also discussed. The 50 recommended research items are categorized by flight phase, technology, and compatibility benefits. The relationship of the TAC recommendations to the previous ATT recommendations is discussed. The bulk of the document contains the 50 recommended research items. For each item, the potential payoff, state of readiness, recommended action, and estimated cost and schedule are given.

An analysis was made to identify airplane research and technology necessary to ensure advanced transport aircraft the capability of accommodating forecast traffic without adverse impact on airport communities. Projections were made of the delay, noise, and emissions impact of future aircraft fleets on typical large urban airports. Design requirements, based on these projections, were developed for an advanced technology, long-haul, subsonic transport. A baseline aircraft was modified to fulfill the design requirements for terminal area compatibility. Technical and economic comparisons were made between these and other aircraft configured to support the study. Research recommendations are given in volume II.

The nine-county San Francisco Bay area is examined in two time periods (1975-1980 and 1985-1990) as a scenario for analyzing the characteristics of an intraurban, commuter-oriented aircraft transportation system. Aircraft have dominated the long-haul passenger market for some time, but efforts to penetrate the very-short-haul intraurban market have met with only token success. Yet, the characteristics of an aircraft transportation system, speed and flexibility, are very much needed to solve the transportation ills of our major urban areas. The aircraft intraurban system is a technically feasible alternative to ground transportation systems. Although requiring some subsidy, it becomes socially viable where substantial commuter traffic exists at ranges of 10 to 15 mi or more and where topographic features constrain ground travel. The general problem areas of community noise, air traffic congestion, ground transportation interface, pollution, and safety appear to have workable solutions.

This document reports on the design of the Diamondback, an aircraft model of a 100-passenger aircraft designed to cruise at 28 ft/s and compete against the 40-passenger HB-40 in the fictional Aeroworld commercial transport market. Unlike conventional aircraft, the Diamondback utilizes an innovative configuration known as the joined wing. The topics addressed include: economic/cost analysis, aerodynamics, weight and structures, propulsion, stability and control, and performance.

Procurement of the UTTAS as designed in prototype models will require changes in the existing aircraft maintenance system to insure repairability at DS level. The UTTAS structural design was studied to assess the army's capability to repair the UTTAS if or when damaged in combat. Analogies are drawn between the complexity of the UTTAS and the Chinook and Skycrane. Historical examples of research and development efforts are used to point out the shortcomings experienced with the 'new technology' associated with helicopters deployed in Vietnam. Criticism of many of those aircraft is correlated directly with the UTTAS to point out that new technology is not necessarily good technology with respect to repairability. The author contends that the new three level aircraft maintenance system that evolved from Vietnam experience is outmoded and incapable of supporting the UTTAS in the short, violent, lethal war scenario in Europe. Recommendations include: a change in management of CMF 67 personnel to provide a large pool of skilled MOS 68 series repairmen; revision of the three level system to provide theater capability for extensive GS airframe repair; revision of TM's to provide standards of serviceability for peacetime and lesser standards for wartime; pursuing new technology in airframe repair; and retention/procurement of a simpler refined technology aircraft.

摘要 :
Two H-34A Helicopters, each with crews of six men, when disassembled and placed on skids which do not raise the silhouette more than four inches could be air-transported in C-124, XC-132 and XC-123 aircraft.
