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. -

Commercial Orbital Transportation Services

By establishing government-industry partnerships, the Commercial Orbital Transportation Services (COTS) program marked a change from the traditional way NASA had worked. Inset photos, right: The COTS program supported two U.S. companies in their efforts to design and build transportation systems to carry cargo to low-Earth orbit. (Top photo—Credit: SpaceX) SpaceX launched its Falcon 9 rocket on May 22, 2012, from Cape Canaveral, Florida. (Second photo) Three days later, the company successfully completed the mission that sent its Dragon spacecraft to the Station. (Third photo—Credit: NASA/Bill Ingalls) Orbital Sciences Corp. sent its Antares rocket on its test flight on April 21, 2013, from a new launchpad on Virginia’s eastern shore. Later that year, the second Antares lifted off with Orbital’s cargo capsule, (Fourth photo) the Cygnus, that berthed with the ISS on September 29, 2013. Both companies successfully proved the capability to deliver cargo to the International Space Station by U.S. commercial companies and began a new era of spaceflight. ISS photo, center left: Benefiting from the success of the partnerships is the International Space Station, pictured as seen by the last Space Shuttle crew that visited the orbiting laboratory (July 19, 2011).

Mahdi Asnaashari Saeide Kazembeigi Mahdi Jamshidiha Amirreza Saffizadeh 952842 978931 688249 937080 Copyright © 2019 by FARAS. Published by the American Institute of Aeronautics and Astronautics, Inc., with Permission Executive Summary This report proposes a turboshaft engine referred to “Sharif TurboShaft 1000 (STS-1000)” as a candidate engine to replace the baseline engine TPE331-10 for the next generation “Hybrid Electric Medium Altitude Long Endurance Search and Rescue UAV” by the year 2025. STS-1000, unlike the baseline engine, is a split single-spool turboshaft engine. The hot gas generator is a single spool with a single stage radial compressor, a reverse annular combustion chamber, and an uncooled single stage axial compressor turbine. The required shaft power is produced by a two stage axial power turbine on a separate spool which passes through the spool of the core engine and is intended to drive a power generator at the cold end of the engine. The air intake is of S-type and the exhaust duct has circular cross section. Compared to TPE331-10, STS-1000 has a higher turbine inlet temperature, a lower stage number for the air compressor, and requires less mass flow rate. -
