Some General Considerations Concerning VTOL Aircraft

1957-01-01
570018
FUNDAMENTAL considerations which govern the power and fuel requirements, maximum speed, safety, and practical utility of types of VTOL aircraft are enumerated and discussed. The most interesting types of VTOL aircraft such as the helicopter are discussed and evaluated in regard to their probable applicability to the various fields of usefulness in view of these fundamental considerations. ...It is recognized that there is an advantage in the power-controlled approaches of VTOL aircraft from small airports under all weather conditions. It is realized that there is research still needed to make the VTOL a more satisfactory aircraft. ...It is realized that there is research still needed to make the VTOL a more satisfactory aircraft.

Convertiplanes and Other VTOL Aircraft

1957-01-01
570017
REVIEW is given of some representative current configurations and propulsion arrangements for VTOL aircraft. Support is urged for a comprehensive development program on VTOL aircraft to cover the spectrum of aircraft flight speeds and promising propulsion arrangements. ...Efforts to reduce the landing and take-off distance requirements of conventional fixed-wing airplanes should continue, he feels, but it should not be accepted as an interim step toward or a substitute for true VTOL aircraft development.

SOME PERFORMANCE AND OPERATING CHARACTERISTICS OF CONVERTIPLANES

1957-01-01
570157
The place of the convertiplane in the VTOL aircraft spectrum between the helicopter and the jet direct-lift airplane is discussed. Performance and operating characteristics are compared for four turbine-powered convertiplane designs having a range of disc loadings from 10 to 160 lbs/sq ft, and capable of hovering flight at 5000 ft on a 95°F day.

HydroLogic Redundant Systems

1965-02-01
650575
This paper considers redundant systems, starting with overall flight control system requirements, and then proceeds via various possible approaches through to a specific concept and its typical applications. Functional, reliability, and safety aspects of a flight control system which are essential to a good redundant scheme are discussed, and the several approaches are compared. The HydroLogics approach is particularly found to offer a simple, versatile, fast acting, and reliable system, based on sound concept and proven hardware. By taking full advantage of these redundant systems, the true potential of high performance vehicles can be realized.

Future Sensing and Information Requirements and System Ideas that Apply to Flight Control

1965-02-01
650585
The paper deals with a general treatment of establishing the instrumentation and associated system requirements for control of future flight vehicles, the challenging pace of instrumentation technology, what one can expect in the way of firm future requirements, what will be required of the instrument developer, and some typical problems of the future. It suggests that this is a fruitful product area, but will require an all out imaginative effort with a high degree of flexibility to stay competitive.

Factors in Selecting Digital or Analog Computation for Flight Control

1965-02-01
650597
Consideration of the factors involved in selection of the flight control computation approach indicates that digital computation offers a degree of flexibility not inherent in analog systems. The purpose of the paper is to present to the flight control designer those factors which indicate the desirability of a digital flight control system. The similarity of the concept to analog systems is discussed as are the reliability and microcircuit advantages of digital computation. The basic point of the paper is that the techniques and components are now available to provide digital computation for the flight control problem.

Development and Flight Test Results of the Tri-Service X-19 V/STOL Aircraft

1965-02-01
650264
A new vertical take-off and landing aircraft, designated the X-19, has been built with high load carrying capacity, high cruise-speed, and extended hover capability. It is a tandem-wing, tilt-propeller vehicle powered by two turbo-shaft engines. The design meets the exacting performance, stability, and control requirements of hover and low-speed flight while maintaining high transport efficiency at cruise. The basic elements of the design are suitable for a series of new operating requirements for military and civil uses. The flight test results of the X-19 confirm the performance and handling predictions and, thus, prove that desired operating characteristics of V/STOL aircraft can be obtained.

650263
A comparison of high and low pressure-ratio nonregenerative and low pressure-ratio regenerative gas turbine engines of the early 1970 vintage has been made for a utility helicopter and a medium fixed wing transport application. Elementary cost and productivity comparisons have been made to reflect the potential of regenerative engines in terms of the overall systems, including cost, maintenance, and fuel savings.

Army Aircraft Systems Development Program

1965-02-01
650249
The Army's aircraft development efforts are directed toward six major systems. The principal thrust is in the vertical and short takeoff and landing concepts, ranging from low to moderate disc loading. The six major aircraft systems are: light observation, surveillance and target acquisition, advanced aerial fire support, utility tactical transport, light tactical transport, and heavy lift. Coupled with these efforts, the Army conducts a number of exploratory and advanced development projects not specifically directed toward any individual system, but which will result in improved small turbine engines, reduction of aircraft vulnerability, noise and vibration abatement, improved controllability, reduction of power train weight, and increased armament effectiveness.

The Use of Off-the-Shelf Aircraft to Meet Army Requirements

1965-02-01
650369
This paper illustrates the economics of Army procurement of commercial aircraft and the advantages to the non-military aircraft operator. The absence of significant compromise of military requirements, and the history of this procurement method is presented. Military airworthiness tests based upon military and FAA standards, and the establishment of common standards, results in significant savings to the government, commercial and private interests. The paper concludes that the majority of the Army's future aircraft needs could be obtained through off-the-shelf programs with the FAA as engineering agency, eliminating problems created when the Navy or Air Force is the engineering agency.
