  • 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.

  • 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.

  • DESCRIPTION Fokker 50
    Fokker 50 - Power Plant DESCRIPTION The aircraft is equipped with two Pratt and Whitney PW 125B turboprop engines, which are enclosed, in wing-mounted nacelles. Each engine drives a Dowty Rotol six-bladed reversible- pitch constant-speed propeller. The engine is essentially a twin-spool turbojet combined with a free power-turbine assembly, which drives the reduction gearbox and propeller via a third concentric shaft. Engine layout Air intake The air intake is located below the propeller spinner. The intake has an anti-icing system. Combustion section The combustion section comprises an annular combustion chamber, fourteen fuel nozzles, and two igniters. Fuel control is through combined mechanical and electronic control systems. High pressure spool This spool comprises a centrifugal compressor and a single stage axial turbine. HP-spool rpm (NH) is governed by fuel metering. The spool drives the HP fuel pump and the lubrication oil pumps. Low pressure spool This spool comprises a centrifugal compressor and a single stage axial turbine. The LP spool is ungoverned; it is free to adapt itself to the operating conditions. LP-spool rpm is designated NL. To ease the gas flow paths and to minimize the gyroscopic moment, the LP spool rotates in a direction opposite to the HP spool and power-turbine shaft. Power turbine The two-stage axial power turbine drives the propeller via the reduction gearbox. The propeller shaft line is set above the engine shaft centerline. Propeller rpm is designated NP. The reduction gearbox also drives an integrated drive generator, a hydraulic pump, a propeller-pitch-control oil pump, a propeller overspeed governor, and the NP indicator.

The centrifugal compressor in tur- bochargers is limited at off-design operating conditions by the inception of flow instabilities causing rotating stall and surge. They occur at reduced engine speeds (low mass flow rates), i.e. typical operating conditions for a better engine fuel economy, harming ICEs efficiency. Moreover, unwanted unsteady pressure loads within the compressor are induced; thereby lowering the com- pressors operating life-time. Amplified noise and vibration are also generated, resulting in a notable discomfort. The thesis aims for a physics-based understanding of flow instabilities and the surge inception phenomena using numerical methods. Such knowledge may permit developing viable surge control technologies that will allow turbocharg- ers to operate safer and more silent over a broader operating range.

FAULK Conducted lAW Air Force Instruction 51-503 EXECUTfVES~Y AIRCRAFT ACCIDENT INVESTIGATION BOARD F-16C+, SN 87-0242 TRUAX FIELD, WISCONSIN 7JUNE2011 On 7 June 2011, at 1316 local time, an F-16C+, serial number 87-0242, impacted the ground approximately 57 nautical miles northwest of Truax Field, Wisconsin. The Mishap Aircraft (MA) and Mishap Pilot {MP), assigned to the 176th Fighter Squadron, 115th Fighter Wing, Truax Field, Wisconsin, were participating in a training mission when the MA experienced a sudden loss of thrust approximately one hour and twenty-three minutes after takeoff. The MP was unable to achieve a successful engine restart. The MP ejected safely and sustained only minor scratches and bruises. The MA impacted near an unoccupied private residence and both were completely destroyed. There were no civilian injuries. The MA was valued at $25,691,100.30. The mishap mission was briefed as a continuation training basic fighter maneuver mission which involved simulated air-to-air "dogfights" between the MP and the mishap wingman, each in their own F -16 aircraft. As the mishap flight prepared to return to base, the MA experienced a sudden loss of thrust. The MP had cockpit indications of an engine failure and immediately began a turn to the nearest suitable runway while simultaneously initiating air start procedures to recover the engine. The MP jettisoned his empty external fuel tanks to reduce drag once clear of a populated area below the MA.

  • Structural Analysis of Load Compressor Blade of Aircraft Auxiliary Power Unit Meha Setiya1, Dr
    International Journal of Scientific & Engineering Research, Volume 6, Issue 2, February-2015 596 ISSN 2229-5518 Structural analysis of load compressor blade of aircraft auxiliary power unit Meha Setiya1, Dr. Beena D. Baloni2, Dr. Salim A. Channiwala3 1Dept. of Mechanical Engineering Sardar Vallabhbhai National Institute of Technology, Surat, Gujarat, India. [email protected] 2,3Dept. of Mechanical Engineering Sardar Vallabhbhai National Institute of Technology, Surat, Gujarat, India [email protected] [email protected] Abstract— Auxiliary power unit is small gas turbine which comprises power section, load compressor and generator system. The present work incorporates stress analysis of impeller blade of the load compressor aircraft APU 131-9A using ANSYS 15. For centrifugal compressor, impeller is main dynamic component. Structural stresses induced in impeller due to combined loading of thermal and inertia forces, affects performance of compressor in terms of efficiency, pressure ratio, service life etc. To explore the effect of this combined loading, structural analysis has been done. Structural analysis of impeller blade gives a vision about critical deformations and critical stresses and their locations. Thermal analysis has also been done to investigate thermal stresses and deformation due to temperature and pressure loads in the blade passage. Both thermal and structural analysis has been done for different materials namely SS 310, INCOLOY 909, Timetal834 and Ti 6-2-4-6. The selection of materials has been done on the basis of strength at high speeds. The results suggest that for particular application of high speed load compressor blade, induced structural stresses are within permissible range throughout the blade only in case of Ti 6-2-4-6.
