Foreword to the First Edition BackgroundThe first flight of the Wright brothers in December marked the beginning of the magnificent evolution of human-controlled, powered flight. The driving forces of this evolution are the ever-growing demands for improvements in 1 Flight performance i. These strong demands continuously furthered the efforts of advancing the aircraft system. The tight interdependency between the performance characteristics of aerovehicle and aeropropulsion systems plays a very important role in this evolution.

Therefore, to gain better insight into the evolution of the aeropropulsion system, one has to be aware of the challenges and advancements of aerovehicle technology.

The AerovehicleA brief review of the evolution of the aerovehicle will be given first. One can observe a continuous trend toward stronger and lighter airframe designs, structures, and materials--from wood and fabric to all-metal structures; to lighter, stronger, and more heat-resistant materials; and finally to a growing use of strong and light composite materials. At the same time, the aerodynamic quality of the aerovehicle is being continuously improved.

To see this development in proper historical perspective, let us keep in mind the following information. In the early years of the 20th century, the science of aerodynamics was in its infancy.

Specifically, the aerodynamic lift was not scientifically well understood. Joukowski and Kutta's model of lift by circulation around the wing and Prandtl's boundary-layer and turbulence theories were in their incipient stages. In Fig. In comparison, birds have an LID ranging from about 5 to The Wright brothers' first human-controlled, powered aircraft had an LID of about 7.

As the LID values increased over the years, sailplanes advanced most rapidly and now are attaining the enormously high values of about 50 and greater. This was achieved by employing ultrahigh wing aspect ratios and aerodynamic profiles especially tailored for the low operational Reynolds and Mach numbers.

In the late s, subsonic transport aircraft advanced to LID values of about 20 by continuously improving the aerodynamic shapes, employing advanced profiles, achieving extremely smooth and accurate surfaces, and incorporating inventions such as the engine cowl and the retractable landing gear.

This was accomplished by innovative wing structures incorporating wing slots and wing flaps that, during the landing process, enlarged the wing area and increased significantly the lift coefficient. Today, the arrowhead-shaped wing contributes to a high lift for landing vortex lift. Also, in the s, work began to extend the high LID value from the subsonic to the transonic flight speed regime by employing the sweptback wing and later, in , the area rule of Whitcomb to reduce transonic drag rise.

I was one of those who had received a formal invitation to give a paper at the conference from Italy's great Gugliemo Marconi, inventor of the wireless telegraph.

All of the world's leading aerodynamicists were invited. This meeting was historic because it marked the beginning of the supersonic age. It was the beginning in the sense that the conference opened the door to supersonics as a meaningful study in connection with supersonic flight, and, secondly, because most developments in supersonics occurred rapidly from then on, culminating in a mere 11 years later--in Captain Charles Yeager's piercing the sound barrier with the X-1 plane in level flight.

In terms of future aircraft development, the most significant paper at the conference proved to be one given by a young man, Dr. Adolf Busemann of Germany, by first publicly suggesting the swept-back wing and showing how its properties might solve many aerodynamic problems at speeds just below and above the speed of sound. Through these investigations, the myth that sonic speed is the fundamental limit of aircraft flight velocity, the sound barrier was overcome. In the late s, the Boeing with swept-back wings had, in transonic cruise speed, an LID value of nearly This great improvement possibility in the aerodynamics of supersonic aircraft can be attributed to applications of artificial stability, to the area rule, and to advanced wing profile shapes that extend laminar flow over a larger wing portion.

The hypersonic speed regime is not fully explored. First, emphasis was placed on winged reentry vehicles and lifting bodies where a high LID value was not of greatest importance. Later investigations have shown that the LID values can be greatly improved. For example, the maximum LID for a "wave rider" is about 6. The Aeropropulsion SystemAt the beginning of this century, steam and internal combustion engines were in existence but were far too heavy for flight application.

The Wright brothers recognized the great future potential of the internal combustion engine and developed both a relatively lightweight engine suitable for flight application and an efficient propeller. Figure 2 shows the progress of the propulsion systems over the years. This great improvement was achieved by engine design structures and materials, advanced fuel injection, advanced aerodynamic shapes of the propeller blades, variable-pitch propellers, and engine superchargers.

The power output of the largest engine amounted to about hp. In the late s and early s, the turbojet engine came into existence. As can be seen from Fig.

The power output of today's largest gas turbine engines reaches nearly , equivalent hp. The increase in flight speed over the years is shown in Fig. In , the Wright brothers built the first military aircraft under government contract.

During World War I, aircraft technology progressed rapidly. The flight speed reached about mph, and the engine power attained hp. After World War I, military interest in aircraft systems dropped, but aircraft technology had reached such a degree of maturity that two nonmilitary application fields could emerge, namely: 1 Commercial aviation, mail and passenger transport first all-metal monoplane for passenger and mail transport, the Junkers F13, in , sold worldwide ;2 Stunt flying leading to general aviation sport and private transportation.

In the period from to , the speed increased from about to mph through evolutionary improvements in vehicle aerodynamics and engine technology, as discussed previously. At the end of World War II, the flight speed of propeller aircraft reached about mph, and the power output of the largest reciprocating engines was about hp.

The first jet-propelled experimental aircraft flew in the summer of the He , and in early , the first prototype jet tighter began flight tests. In , mass-produced jet fighters reached a speed of about mph. In the early s, jet aircraft transgressed the sonic speed.

In the mids, the first supersonic jet bomber B Hustler appeared, and later the XB reached about Mach 3. Also during the s, after more than 15 years of military development, gas turbine technology had reached such a maturity that the following commercial applications became attractive: 1 commercial aircraft, e. In the s, the high-bypass-ratio engine appeared, which revolutionized military transportation the C5A transport aircraft.

At the end of the s, based on the military experience with high-bypass-ratio engines, the second generation of commercial jet aircraft came into existence, the widebody aircraft. An example is the Boeing with a large passenger capacity of nearly By that time, the entire commercial airline fleet used turbine engines exclusively. Advantages for the airlines were as follows:1 Very high overall efficiency and, consequently, a long flight range with economical operation.

By the end of the s, the entire business of passenger transportation was essentially diverted from ships and railroads to aircraft. In the s, the supersonic Concorde with a flight speed of mph the third generation of commercial transport appeared with an equivalent output of about , hp.

SummaryIn hindsight, the evolution of aerovehicle and aeropropulsion systems looks like the result of a master plan. The evolution began with the piston engine and propeller, which constituted the best propulsion system for the initially low flight speeds, and had an outstanding growth potential up to about mph.

In the early s, when flight technology reached the ability to enter into the transonic flight speed regime, the jet engine had just demonstrated its suitability for this speed regime. A vigorous jet engine development program was launched. Soon the jet engine proved to be not only an excellent transonic but also a supersonic propulsion system. This resulted in the truly exploding growth in flight speed, as shown in Fig. It is interesting to note that military development preceded commercial applications by years for both the propeller engine and the gas turbine engine.

The reason was that costly, high-risk, long-term developments conducted FOREWORD xxi by the military sector were necessary before a useful commercial application could be envisioned. After about 75 years of powered flight, the aircraft has outranked all other modes of passenger transportation and has become a very important export article of the United States.

The evolutions of both aerovehicle and aeropropulsion systems have in no way reached a technological level that is close to the ultimate potential! The evolution will go on for many decades toward capabilities far beyond current feasibility and, perhaps, imagination. How Jet Propulsion Came into ExistenceThe idea of airbreathing jet propulsion originated at the beginning of the 20th century.

Several patents regarding airbreathing jet engines had been applied for by various inventors of different nationalities who worked independently of each other. From a technical standpoint, airbreathing jet propulsion can be defined as a special type of internal combustion engine that produces its net output power as the rate of change in the kinetic energy of the engine's working fluid.

The working fluid enters as environmental air that is ducted through an inlet diffuser into the engine; the engine exhaust gas consists partly of combustion gas and partly of air. The exhaust gas is expanded through a thrust nozzle or nozzles to ambient pressure. A few examples of early airbreathing jet propulsion patents are as follows:1 In , Lorin patented a jet engine that was based on piston machinery Fig.

Guillaume patented a jet engine based on turbomachinery; the intake air was compressed by an axial-flow compressor followed by a combustor and an axial-flow turbine driving the compressor Fig. These patents clearly described the airbreathing jet principle but were not executed in practice. The reason lies mainly in the previously mentioned strong interdependency between aerovehicle and aeropropulsion systems.

Elements of Propulsion: Gas Turbines and Rockets (AIAA Education Series)

A gas turbine , also called a combustion turbine , is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are:. A fourth component is often used to increase efficiency on turboprops and turbofans , to convert power into mechanical or electric form on turboshafts and electric generators , or to achieve greater thrust-to-weight ratio on afterburning engines. The basic operation of the gas turbine is a Brayton cycle with air as the working fluid : atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature pressurized gas enters a turbine, producing a shaft work output in the process, used to drive the compressor; the unused energy comes out in the exhaust gases that can be repurposed for external work, such as directly producing thrust in a turbojet engine , or rotating a second, independent turbine known as a power turbine that can be connected to a fan, propeller, or electrical generator. The purpose of the gas turbine determines the design so that the most desirable split of energy between the thrust and the shaft work is achieved.
