AeroTech is your passport to explore the most remarkable advancements in aerospace technology. Form supersonic aircraft to sustainable aviation and propulsion, AeroTech covers it all.

This document supplements ARP85, to extend its use in the design of ECS for supersonic transports. The ECS provides an environment controlled within specified operational limits of comfort and safety, for humans, animals, and equipment.

In order for the supersonic transport to be economically feasible, the cost of the fuel should be essentially equivalent to ASTM type A and type A-1 prices. ...The results of the survey indicated that some of the commercial aviation kerosene fuel being supplied to the commercial subsonic jets of today may be satisfactory for use in the supersonic transport.

With the advent of the supersonic transport accessory power system, designers will be faced with a quantum jump in power requirements and environmental conditions. ...The requirements and operating conditions for secondary power on the supersonic transport are discussed and subsystem designs are presented.

The supersonic transport is a larger and more complex airplane than the present-day subsonic transport. ...Systems and support equipment which are unique to the supersonic transport are described.

Laboratory experiments with projectiles fired through an ice-fog cloud were used to study the variation of frictional charging with air speed at supersonic speeds. These experiments demonstrated that the charge imparted by each particle decreases with increasing speed at supersonic speeds, apparently because of ice crystal melting on impact. ...These experiments demonstrated that the charge imparted by each particle decreases with increasing speed at supersonic speeds, apparently because of ice crystal melting on impact. Flight instrumentation has been designed and fabricated to measure electrification parameters and effects on a supersonic test aircraft. ...Flight instrumentation has been designed and fabricated to measure electrification parameters and effects on a supersonic test aircraft. The instrumentation measures, charging rate, discharging rate, charge per particle, aircraft potential, streamer current and number of streamer pulses, variation of effective frontal area, and noise spectrum.

General technical requirements are presented which led to the selection of titanium alloys as the basic structural material for a Mach 2.7 supersonic transport. Discussion includes important material properties such as strength, toughness, corrosion and stress corrosion resistance, metallurgical stability, and fatigue.

With the supersonic airplane's skin hot enough to broil a steak, the cabin atmosphere inside has to be as comfortable and safe as it is in subsonic jet transports.

New light is shed on the problems of achieving profitable use of the SST's annual seat mile capability and the difficulties in developing a schedule pattern minimizing adverse effects of necessary subsonic segments. The supersonic is considered in terms of acceptable schedule times versus optimum utilization, fixed costs as related to purchase price and amortization, and break-even load factors versus capacity generated and per mile operating costs.

THE ramjet excels all other powerplants for sustained propulsion at supersonic speeds. Ramjets feature high power per unit frontal area and per unit weight and high specific impulse.

This paper outlines some of the problems of installing engines on the first supersonic bomber. Emphasis is on the new problems. The treatment is more historical and philosophical than technical.

This paper discusses the design considerations for supersonic transport aircraft of four types-one with a variable sweep wing and three with fixed wings.

It is shown that performance requirements will exert great pressure toward incorporation of variable geometry features in the supersonic transport configuration.

SST design and results of recent progress on an advanced supersonic transport design. The results are shown of changing from a double-delta 2.7 Mach configuration to a modified arrow-wing 2.2 Mach design.

Potential fuel system problems peculiar to the supersonic transport such as fuel boiling, spontaneous ignition, deposit formation, lubricity, and combustion characteristics are reviewed.

One of the three National Aeronautical R&D Goals of the President's Office of Science and Technology Policy was the attainment of long-distance supersonic cruise capability. NASA was asked to lead the development of a “Technology Roadmap” for this goal.

The impact of supersonic commercial service to be provided by the Concorde and TU 144 SST is going to demonstrate throughout the world the advantages offered by supersonic travel for both business and recreation. ...The impact of supersonic commercial service to be provided by the Concorde and TU 144 SST is going to demonstrate throughout the world the advantages offered by supersonic travel for both business and recreation. Public acceptance will stimulate interest to proceed with a second generation design that meets updated economic and ecological standards.

Two powered-lift concepts, the tandem fan and the longitudinally-arrayed ejector, are integrated with two existing fighter aircraft, the F-l4A and F-16A respectively, to indicate the benefits and/or penalties involved with providing STOVL capability to CTOL aircraft. It is shown that properly designed powered-lift aircraft can achieve either comparable or superior mission performance relative to CTOL aircraft.
