  • 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.

  • 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.

  • Helicopter Turboshafts
    Helicopter Turboshafts Luke Stuyvenberg University of Colorado at Boulder Department of Aerospace Engineering The application of gas turbine engines in helicopters is discussed. The work- ings of turboshafts and the history of their use in helicopters is briefly described. Ideal cycle analyses of the Boeing 502-14 and of the General Electric T64 turboshaft engine are performed. I. Introduction to Turboshafts Turboshafts are an adaptation of gas turbine technology in which the principle output is shaft power from the expansion of hot gas through the turbine, rather than thrust from the exhaust of these gases. They have found a wide variety of applications ranging from air compression to auxiliary power generation to racing boat propulsion and more. This paper, however, will focus primarily on the application of turboshaft technology to providing main power for helicopters, to achieve extended vertical flight. II. Relationship to Turbojets As a variation of the gas turbine, turboshafts are very similar to turbojets. The operating principle is identical: atmospheric gases are ingested at the inlet, compressed, mixed with fuel and combusted, then expanded through a turbine which powers the compressor. There are two key diferences which separate turboshafts from turbojets, however. Figure 1. Basic Turboshaft Operation Note the absence of a mechanical connection between the HPT and LPT. An ideal turboshaft extracts with the HPT only the power necessary to turn the compressor, and with the LPT all remaining power from the expansion process. 1 of 10 American Institute of Aeronautics and Astronautics A. Emphasis on Shaft Power Unlike turbojets, the primary purpose of which is to produce thrust from the expanded gases, turboshafts are intended to extract shaft horsepower (shp).

Mitchell Lewis Research Center Cleveland, Ohio i I Prepared for the ! National Business Aircraft Meeting sponsored by the Society of Automotive Engineers Wichita, Kansas, April 7-10, 1981 LOW AND HIGH SPEED PROPELLERS FOR GENERAL AVIATION - PERFORMANCE POTENTIAL AND RECENT WIND TUNNEL TEST RESULTS by Robert J. Jeracki and Glenn A. Mitchell National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio 441 35 THE VAST MAJORlTY OF GENERAL-AVIATION AIRCRAFT manufactured in the United States are propel- ler powered. Most of these aircraft use pro- peller designs based on technology that has not changed significantlv since the 1940's and early 1950's. This older technology has been adequate; however, with the current world en- ergy shortage and the possibility of more stringent noise regulations, improved technol- ogy is needed. Studies conducted by NASA and industry indicate that there are a number of improvements in the technology of general- aviation (G.A.) propellers that could lead to significant energy savings. New concepts like blade sweep, proplets, and composite materi- als, along with advanced analysis techniques have the potential for improving the perform- ance and lowering the noise of future propel- ler-powererd aircraft that cruise at lower speeds. Current propeller-powered general- aviation aircraft are limited by propeller compressibility losses and limited power out- put of current engines to maximum cruise speeds below Mach 0.6. The technology being developed as part of NASA's Advanced Turboprop Project offers the potential of extending this limit to at least Mach 0.8.

Krakowska 110/114, 02-256 Warsaw, Poland [email protected] Abstract This work presents selected results of I-31T propulsion flight tests, obtained in the framework of ESPOSA (Efficient Systems and Propulsion for Small Aircraft) project. I-31T test platform was equipped with TP100, a 180 kW turboprop engine. Engine installation design include reverse flow inlet and separator, controlled from the cockpit, that limited ingestion of solid particulates during ground operations. The flight tests verified proper air feed to the engine with the separator turned on and off. The carried out investigation of the intake system excluded possibility of hazardous engine -op eration, such as compressor stall, surge or flameout and potential airflow disturbance causing damaging vibration of the engine body. Finally, we present evaluation of total power losses associated with engine integration with the airframe.

  • Introduction to Turboprop Engine Types
    INTRODUCTION TO TURBOPROP ENGINE TYPES The turbopropeller engine consists of a gas turbine engine driving a propeller. Most of the energy of the gas flow (air and burned fuel) is used to drive the propeller and compressor. The remaining energy, in the form of differential velocity of the airflow exiting the turbine, provides a small amount of residual thrust (effectively, a small amount of jet propulsion). Additional information on the specifics of the gas turbine cycle is provided elsewhere in this training package. There are two basic types of turboprop engines: 1. Single shaft 2. Free turbine The main difference between single shaft and free turbines is in the transmission of the power to the propeller. In the majority of turboprops, the fuel pump is driven by the engine. This is known as "direct drive.” In some older types of engines, the fuel pump is driven by the propeller, which can affect proper response to an engine failure. Refer to type-specific procedures. Single Shaft. In a single-shaft engine, the propeller is driven by the same shaft (spool) that drives the compressor. Because the propeller needs to rotate at a lower RPM than the turbine, a reduction gearbox reduces the engine shaft rotational speed to accommodate the propeller through the propeller drive shaft. Free Turbine. In a free-turbine engine, the propeller is driven by a dedicated turbine. A different turbine drives the compressor; this turbine and its compressor run at near-constant RPM regardless of the propeller pitch and speed. Because the propeller needs to rotate at lower RPM than the turbine, a reduction gearbox converts the turbine RPM to an appropriate level for the propeller.

  • Jet Propulsion Engines
    JET PROPULSION ENGINES 5.1 Introduction Jet propulsion, similar to all means of propulsion, is based on Newton’s Second and Third laws of motion. The jet propulsion engine is used for the propulsion of aircraft, m issile and submarine (for vehicles operating entirely in a fluid) by the reaction of jet of gases which are discharged rearw ard (behind) with a high velocity. A s applied to vehicles operating entirely in a fluid, a momentum is imparted to a mass of fluid in such a manner that the reaction of the imparted momentum furnishes a propulsive force. The magnitude of this propulsive force is termed as thrust. For efficient production of large power, fuel is burnt in an atmosphere of compressed air (combustion chamber), the products of combustion expanding first in a gas turbine which drives the air compressor and then in a nozzle from which the thrust is derived. Paraffin is usually adopted as the fuel because of its ease of atomisation and its low freezing point. Jet propulsion was utilized in the flying Bomb, the initial compression of the air being due to a divergent inlet duct in which a sm all increase in pressure energy w as obtained at the expense of kinetic energy of the air. Because of this very limited compression, the thermal efficiency of the unit was low, although huge power was obtained. In the normal type of jet propulsion unit a considerable improvement in efficiency is obtained by fitting a turbo-com pressor which w ill give a com pression ratio of at least 4:1.
