Elements of Propulsion: Gas Turbines and Rockets_chapter10_Inlets, Nozzles, and Combustion Systems

نویسنده: Jack D. Mattingly & Hans von Ohain

کد کتاب.: 22778#

شرح: The inlet and exhaust nozzle are the two engine components that directly interface with the internal airflow and the flow about the aircraft. In fact, integration of the engine and the airframe is one of the most complex problems and has a major impact on the performance of the aircraft system. Many technical books, reports, articles, etc., are available in open literature (public domain) that concentrate on only small parts of this major technical challenge. This chapter identifies the major design considerations of inlets and exhaust nozzles and pre- sents basic analysis tools for their preliminary sizing and design.

شرح: In general, turbomachinery is classified as all those devices in which energy is transferred either to or from a continuously flowing fluid by the dynamic action of one or more moving blade rows. 37 The word turbo or turbinis is of Latin origin and implies that which spins or whirls around. Essentially, a rotating blade row or rotor changes the total enthalpy of the fluid moving through it by either doing work on the fluid or having work done on it by the fluid, depending on the effect required of the machine.

Elements of Propulsion: Gas Turbines and Rockets_chapter8_Engine Performance Analysis

نویسنده: Jack D. Mattingly & Hans von Ohain

کد کتاب.: 22776#

شرح: This chapter is concerned with predicting the performance of a gas turbine engine and obtaining performance data similar to Figs. 1.14a-l.14e, 1.1ha, and 1.15b and the data contained in Appendix B. The analysis required to obtain engine performance is related to, but very different from, the parametric cycle analysis of Chapters 5 and 7.

کد کتاب.: 22775#

شرح: In Chapter 5, we idealized the engine components and assumed that the working fluid behaved as a perfect gas with constant specific heats. These ideal- izations and assumptions permitted the basic parametric analysis of several types of engine cycles and the analysis of engine performance trends. In Chapter 6, we looked at the variation of specific heat with temperature and fuel/air ratio and developed component models and figures of merit.

شرح: In Chapter 5, we idealized the engine components and assumed that the working fluid behaved as a perfect gas with constant specific heats. These ideal- izations and assumptions permitted the basic cycle analysis of several types of engines and the analysis of engine performance trends. In this chapter, we will develop the analytical tools that allow us to use realistic assumptions as to com- ponent losses and to include the variation of specific heats.

شرح: Cycle analysis studies the thermodynamic changes of the working fluid (air and products of combustion in most cases) as it flows through the engine. It is divided into two types of analysis: parametric cycle analysis (also called design- point or on-design) and engine performance analysis (also called off-design).

کد کتاب.: 22772#

شرح: The introductory fundamentals of aircraft propulsion systems are covered in this chapter. Emphasis is placed on propulsion systems that operate on the so-called Brayton cycle. Such systems include turbojets, turboprops, turbofans, ramjets, and combinations thereof. Before taking up the thermodynamic pro- cesses involved in these systems, we consider the forces acting on a propulsive duct and the effect of installation on the net propulsive force.

شرح: The operation of gas turbine engines and of rocket motors is governed by the laws of mechanics and thermodynamics. The field of mechanics includes the mechanics of both fluids and solids. However, since the process occurring in most propulsion devices involves a flowing fluid, our emphasis will be on fluid mechanics or, more specifically, gas dynamics.

شرح: The types of rocket propulsion and basic parameters used in performance evaluation of rocket propulsion are described in this chapter. First, the concepts of thrust, effective exhaust velocity, and specific impulse are presented for a gaseous continuum leaving a rocket engine. These concepts are covered in more detail than that contained in Chapter 1.

شرح: The Random House College Dictionary defines propulsion as "the act of propelling, the state of being propelled, a propelling force or impulse" and defines the verb propel as "to drive, or cause to move, forward or onward. ''1 From these definitions, we can conclude that the study of propulsion includes the study of the propelling force, the motion caused, and the bodies involved. Propulsion involves an object to be propelled plus one or more additional bodies, called propellant.
