CHAPTER 9 Design and Optimization of Turbo Compressors
CHAPTER 9 Design and optimization of Turbo compressors C. Xu & R.S. Amano Department of Mechanical Engineering, University of Wisconsin-Milwaukee, USA. Abstract A compressor has been refereed to raise static enthalpy and pressure. A successful compressor design greatly benefi ts the performance of the whole power system. Lean design methodologies have been used for industrial power system design. The compressor designs require benefi t to both OEM and customers, i.e. lowest cost for both OEM and end users and high effi ciency in all operating range of the compressor. The compressor design and optimization are critical for the new com- pressor development and compressor upgrade. The design experience and design considerations are also critical for a successful compressor design. The design experience can accelerate compressor lean design process. An optimization pro- cess is discussed to design compressor blades in turbo machinery. The compressor design process is not only an aerodynamic optimization, but structure analyses also need to be combined in the optimization. This chapter discusses an aerodynamic and structure integration optimization process. The design method consists of an airfoil shape optimization and a three-dimensional gradient-based optimization coupled with Navier–Stokes solvers. A model airfoil of a transonic compressor is designed by using this approach, with an effi ciency improvement. Airfoil sections were stacked up to a three-dimensional rotor blade of a compressor. The effi ciency is improved over a wide range of mass fl ow. The results indicate that the optimiza- tion process can provide improved design and can be integrated into a compressor design procedure. -

Propeller Operation and Malfunctions Basic Familiarization for Flight Crews
PROPELLER OPERATION AND MALFUNCTIONS BASIC FAMILIARIZATION FOR FLIGHT CREWS INTRODUCTION The following is basic material to help pilots understand how the propellers on turbine engines work, and how they sometimes fail. Some of these failures and malfunctions cannot be duplicated well in the simulator, which can cause recognition difficulties when they happen in actual operation. This text is not meant to replace other instructional texts. However, completion of the material can provide pilots with additional understanding of turbopropeller operation and the handling of malfunctions. GENERAL PROPELLER PRINCIPLES Propeller and engine system designs vary widely. They range from wood propellers on reciprocating engines to fully reversing and feathering constant- speed propellers on turbine engines. Each of these propulsion systems has the similar basic function of producing thrust to propel the airplane, but with different control and operational requirements. Since the full range of combinations is too broad to cover fully in this summary, it will focus on a typical system for transport category airplanes - the constant speed, feathering and reversing propellers on turbine engines. Major propeller components The propeller consists of several blades held in place by a central hub. The propeller hub holds the blades in place and is connected to the engine through a propeller drive shaft and a gearbox. There is also a control system for the propeller, which will be discussed later. Modern propellers on large turboprop airplanes typically have 4 to 6 blades. Other components typically include: The spinner, which creates aerodynamic streamlining over the propeller hub. The bulkhead, which allows the spinner to be attached to the rest of the propeller. -

CHAPTER 10 Advances in Understanding the Flow in A
CHAPTER 10 Advances in understanding the fl ow in a centrifugal compressor impeller and improved design A. Engeda Turbomachinery Lab, Michigan State University, USA. Abstract The last 60 years have seen a very high number of experimental and theoretical studies of the centrifugal impeller fl ow physics at government, industry and uni- versity levels, which have been extensively documented. As Robert Dean, one of the well-known impeller aerodynamists stated, “The centrifugal impeller is prob- ably the most complex fl uid machine built by man”. Despite this, it is still the widest used turbomachinery and continues to be a major research and develop- ment topic. Computational fl uid dynamics has now matured to the point where it is widely accepted as a key tool for aerodynamic analysis. Today, with the power of modern computers, steady-state solutions are carried out on a routine basis, and can be considered as part of the design process. The complete design of the impeller requires a detailed understanding of the fl ow in the impeller and aerody- namic analysis of the fl ow path and structural analysis of the impeller including the blades and the hub. This chapter discusses the developments in the understand- ing of the fl ow in a centrifugal impeller and the contributions of this knowledge towards better and advanced impeller designs. 1 Introduction Centrifugal compressors have the widest compressor application area. They are reliable, compact, and robust; they have better resistance to foreign object dam- age; and are less affected by performance degradation due to fouling. They are found in small gas turbine engines, turbochargers, and refrigeration chillers and are used extensively in the petrochemical and process industry. -
Comparison of Helicopter Turboshaft Engines
Comparison of Helicopter Turboshaft Engines John Schenderlein1, and Tyler Clayton2 University of Colorado, Boulder, CO, 80304 Although they garnish less attention than their flashy jet cousins, turboshaft engines hold a specialized niche in the aviation industry. Built to be compact, efficient, and powerful, turboshafts have made modern helicopters and the feats they accomplish possible. First implemented in the 1950s, turboshaft geometry has gone largely unchanged, but advances in materials and axial flow technology have continued to drive higher power and efficiency from today's turboshafts. Similarly to the turbojet and fan industry, there are only a handful of big players in the market. The usual suspects - Pratt & Whitney, General Electric, and Rolls-Royce - have taken over most of the industry, but lesser known companies like Lycoming and Turbomeca still hold a footing in the Turboshaft world. Nomenclature shp = Shaft Horsepower SFC = Specific Fuel Consumption FPT = Free Power Turbine HPT = High Power Turbine Introduction & Background Turboshaft engines are very similar to a turboprop engine; in fact many turboshaft engines were created by modifying existing turboprop engines to fit the needs of the rotorcraft they propel. The most common use of turboshaft engines is in scenarios where high power and reliability are required within a small envelope of requirements for size and weight. Most helicopter, marine, and auxiliary power units applications take advantage of turboshaft configurations. In fact, the turboshaft plays a workhorse role in the aviation industry as much as it is does for industrial power generation. While conventional turbine jet propulsion is achieved through thrust generated by a hot and fast exhaust stream, turboshaft engines creates shaft power that drives one or more rotors on the vehicle. -
