Solar Thermal Dish Steam Turbine Engine
The document summarizes a solar steam turbine system equipped with concentrating solar power (CSP) technology specially designed for medium solar insolations in humid tropical countries. The parabolic dish systems use satellite-like mirror dishes to focus light onto a central receiver, achieving high conversion efficiencies up to 30%. A 10-25 kW system has a 10 meter diameter dish. It can run individually or be grouped for small or utility-scale power applications, though intermittent clouds can weaken the concentrated solar flux.
Working cycle and airflow
The document discusses the working cycle and airflow of a gas turbine engine. It describes the four stages of the cycle: induction, compression, combustion, and exhaust. During compression, temperature rises as pressure increases and volume decreases. Combustion increases temperature at constant pressure and increased volume. Expansion decreases temperature and pressure as volume increases. An airflow diagram traces these temperature and pressure changes through the engine as velocity changes. Nozzles and venturis are used to convert energy from combustion gases to kinetic energy where supersonic speeds occur. The basic design uses a straight-through airflow system for compact size and use of bypass principles.
Quasi turbine engine
The Saint-Hilaire family patented the Quasi turbine engine in 1996 as an improvement on the standard Wankel or rotary engine. The Quasi turbine uses a four-element rotor within a housing to divide the space into four combustion chambers. It operates on a continuous combustion principle with no vibrations or dead times. The engine aims to be compact, efficient, and able to run on multiple fuel types with high torque at low RPM.

Salient Energy Bio-Conversion Processes Limiting Gas Turbine Engine Performan...
Fuel energy conversion processes in gas turbines are not limited to those occurring in the combustion unit. It however extends to processes involving microbial conversion of fuel components and subsequent accumulation of biological material. This salient form of energy conversion occurs majorly in the fuel storage tank and along the fuel systems, where it exert effects such as metal corrosion in the tank, combustion chamber and downstream unit of the turbine, degradation of fuel components, fuel destabilization, clogging of fuel filtering and distribution units and other fuel physical and chemical changes. Of recent concerns are gas turbines operating on biofuels and blends, since biofuels are said to be more highly susceptibility to biodegradation than conventional fuels. This paper aims to review microbial contamination in gas turbines in recent years and discuss the effects of fuel quality on gas turbine performance and efficiency as well as highlight the benefits that can be gained from enhanced predictive maintenance and control.

Vextec Small Gas Turbine Testing
This presentation discusses using small turbine engine testing to evaluate new gas turbine engine design technologies and replicate failure mechanisms seen in fielded components in a more cost effective and timely manner than full scale engine testing. Key points include:
1) Small turbine testing can reproduce realistic operating conditions to test components to failure multiple times quickly and inexpensively, filling the gap between initial design testing and full scale testing.
2) The methodology was demonstrated to successfully replicate compressor blade corrosion damage and failures seen in fielded USAF engines within 60-90 days of testing.
3) The benefits of small turbine testing include identifying issues earlier, improving full scale test validity, accelerating design certification, and providing more engine-relevant results

This document contains 51 multiple choice questions about gas turbine engine fundamentals. The questions cover topics like engine sections (hot vs cold), compressor types and speeds (N1, N2), turbine operation, nozzle flow properties, cycles (Brayton), and key terms (Pt7, ram effect). Correct answers are provided along with short explanations for each question drawing from references like Rolls Royce and Jeppesen textbooks.
Gas Turbine
Gas turbines work by compressing air, heating it through combustion, and using the expanding hot gases to power a turbine. The key components are a compressor, combustion chamber, and turbine. In the compressor, air is compressed which is then mixed with fuel and ignited in the combustion chamber. The hot gases expand through the turbine, which converts the energy to power the compressor and provide output work to drive loads like generators or propellers. Variations include closed cycle systems which recirculate working fluid through a heat exchanger. Gas turbines have high power-to-weight ratios but lower efficiencies compared to reciprocating engines.

1. The story of a flood is found in many cultures around the world, including Hindu, Sumerian, Biblical, and Mayan traditions. This suggests there was an earlier advanced civilization that was able to build large boats and preserve species.
2. Hindus developed the story of the Matsya avatar of Vishnu logically over 10 incarnations, showing evolution from a fish to fully civilized man. This was over 2000 years before Darwin's theory of evolution.
3. Ancient Sumerians, Mayans and Egyptians said they originated elsewhere or were taught civilization by outsiders. Evidence suggests this earlier civilization was located in South India.

Abstract This paper deals with a method of diagnostics and focuses on the estimation of the depletion or exhaustion of service life of components of gas turbine engine. During operation of the gas turbine engine the critical components of the engine; blades, discs, shafts, wheels, gears, gearboxes and drive assemblies experience the action of centrifugal and gas forces that bring about tension, bending and turning moments. They also experience thermal loads of high intensity that has negative effect on the strength of the materials of the components. The strength of these components defines the reliability of the engine. The forces and thermal loads acting on the critical elements lead to the depletion of the service life of these elements. Hence the estimation of the remaining service life of gas turbine engine components. Keywords: Blades, critical components, damage, depletion, gas turbine engine, failure, service life, typical flight
