An experimental study on kerosene based pulse detonation engineIAEME Publication
This document summarizes an experimental study on a kerosene-based pulse detonation engine. The study tested three equivalence ratios of kerosene and air mixtures. Pressure measurements at different locations along the detonation tube are presented and compared to theoretical Chapman-Jouguet detonation pressures from a NASA chemical equilibrium program. For equivalence ratios of 1.0 and 1.14, the pressure measurements indicate a deflagration to detonation transition occurred before the second measurement location, matching detonation pressures. This confirms stable detonation was achieved in the pulse detonation engine setup.
AN EXPERIMENTAL STUDY ON KEROSENE BASED PULSE DETONATION ENGINE IAEME Publication
The paper summarizes the experimental study on kerosene based pulse detonation engine in a tube for three different equivalence ratios. The kerosene was vaporized in a pre-evaporator before injected into combustion chamber.
Pre-heated air was injected through a nozzle into the detonation tube. The charged tube was electrically ignited near the injector end. To enhance the DDT and to reduce the transition distance Shchelkin spiral was used inside the tube.
Comparison of measured pressure at different locations of the tube with the CEA values were made that confirms to have
crossed the CJ point and provide a stable detonation.
Review on Recent Advances in Pulse Detonation EnginesBBIT Kolkata
Pulse detonation engines (PDEs) are new exciting propulsion technologies for future propulsion applications. The operating cycles
of PDE consist of fuel-air mixture, combustion, blowdown, and purging. The combustion process in pulse detonation engine is the
most important phenomenon as it produces reliable and repeatable detonation waves.The detonation wave initiation in detonation
tube in practical system is a combination of multistage combustion phenomena. Detonation combustion causes rapid burning of
fuel-air mixture, which is a thousand times faster than deflagration mode of combustion process. PDE utilizes repetitive detonation
wave to produce propulsion thrust. In the present paper, detailed review of various experimental studies and computational analysis
addressing the detonation mode of combustion in pulse detonation engines are discussed. The effect of different parameters on
the improvement of propulsion performance of pulse detonation engine has been presented in detail in this research paper. It is
observed that the design of detonation wave flow path in detonation tube, ejectors at exit section of detonation tube, and operating
parameters such as Mach numbers aremainly responsible for improving the propulsion performance of PDE. In the present review
work, further scope of research in this area has also been suggested.

This document is an industrial training report submitted by Amardeep Singh to Gurukul Vidyapeeth Institute of Engineering and Technology. It describes Amardeep's 6-month internship at the Terminal Ballistics Research Laboratory in Chandigarh, India, where he worked under the guidance of Mr. Munesh Kumar Patle. The internship involved introductory study of pulse detonation engine theory and the design and development of a swirl injector for a pulse detonation engine. Terminal Ballistics Research Laboratory works on advanced armament technologies for the Indian defense sector.
The document discusses fundamentals of pulse detonation engines (PDEs) and their advantages over other propulsion systems. A PDE works by injecting a fuel-oxidizer mixture, initiating detonation with an ignition source, and allowing the detonation wave to move through the chamber. This rapidly combusts the mixture at nearly constant volume, providing higher thermodynamic efficiency than gas turbine engines. PDEs offer benefits such as increased efficiency, thrust, and mach range compared to turbojets and could enable supersonic and hypersonic aircraft.
Detonation occurs when the combustion process moves too quickly in an engine cylinder, causing abnormally high pressure and temperatures. This happens if fuel ignites before the scheduled ignition of the spark plug. Detonation can damage engine components and is caused by factors like improper ignition timing, a lean air-fuel mixture, low octane fuel, and high exhaust back pressure. Engines can be protected from detonation by using higher octane fuel, retarding the ignition timing, cooling the air charge, and ensuring a proper fuel supply. Pre-ignition is a related issue where the fuel ignites prematurely due to hot spots in the combustion chamber rather than the spark plug.
Stress Analysis of Pulse Detonation Engine TubeIJMER
The document discusses stress analysis of pulse detonation engine tubes. It analyzes the stresses developed in the tube due to pressure buildup during detonation. Specifically:
1) It calculates the axial, circumferential, and radial stresses in a selected stainless steel tube with 100mm internal diameter and 6mm thickness under 100 bar of pressure.
2) The maximum axial stress developed is 177x10^6 N/m^2, within the material yield stress of 215 MPa.
3) Graphs show the stresses increase linearly with pressure and the selected tube can withstand pressures up to 100 bar at temperatures up to 400°C.
Exergetic efficiency analysis of hydrogen–air detonation in pulse detonation ...BBIT Kolkata
Exergy losses during the combustion process, heat transfer, and fuel utilization play a vital role in the analysis of the
exergetic efficiency of combustion process. Detonation is thermodynamically more efficient than deflagration mode of
combustion. Detonation combustion technology inside the pulse detonation engine using hydrogen as a fuel is energetic
propulsion system for next generation. In this study, the main objective of this work is to quantify the exergetic efficiency
of hydrogen–air combustion for deflagration and detonation combustion process. Further detonation parameters are
calculated using 0.25, 0.35, and 0.55 of H2 mass concentrations in the combustion process. The simulations have been
performed for converging the solution using commercial computational fluid dynamics package Ansys Fluent solver. The
details of combustion physics in chemical reacting flows of hydrogen–air mixture in two control volumes were simulated
using species transport model with eddy dissipation turbulence chemistry interaction. From these simulations it was
observed that exergy loss in the deflagration combustion process is higher in comparison to the detonation combustion
process. The major observation was that pilot fuel economy for the two combustion processes and augmentation of
exergetic efficiencies are better in the detonation combustion process. The maximum exergetic efficiency of 55.12%,
53.19%, and 23.43% from deflagration combustion process and from detonation combustion process, 67.55%, 57.49%,
and 24.89%, are obtained from aforesaid H2 mass fraction. It was also found that for lesser fuel mass fraction higher
exergetic efficiency was observed.

Review: Composite Flywheel for High Speed ApplicationAM Publications
Flywheel is a device to smoothen the cyclic fluctuation of speed change when delivering constant output
power from the engine. It has no influence on the mean speed of the prime mover. It has no influence on the varying
load demand on the prime mover or the delivered power from the prime mover. In the forgoing discussion, it is
observed that turning moment diagrams for the cycle show period during which torque is in excess of the mean torque
responsible for the constant power output and also periods during which the torque is less than the mean torque. Thus
the speed of the flywheel would increase during period of excess of torque during the cycle and the speed will fall
during the period of the deficit torque during the cycle. Thus a flywheel stores energy and releases energy during the
cycle without affecting mean energy output. Thus a properly designed flywheel has to ensure the cyclic fluctuations of
speed within prescribed limits preferably as small as possible. The main objective of our project is to reduce weight of
automobile by using composite material. In this Project Work taking Flywheel as an Automobile component and
applying FEA analysis using ANSYS to optimize weight and strength of flywheel. Here Performing Analysis on metal
flywheel, carbon fiber flywheel and composite i.e. metal and carbon fiber flywheel. By using ANSYS stresses obtained
& compared with analytical calculations, also weight is compared. Composite flywheel made from steel rim & carbon
fiber body will be safe for automobile applications like F1 car. From analysis & analytical results composite flywheel
for automobile can be selected.

It reviews relevant literature on propeller analysis and discusses defining the problem of stress distribution on propeller surfaces from varying hydrostatic pressures. Key points covered include material selection for the
Modeling and Stress Analysis Of Crankshaft Using FEM Package ANSYSIRJET Journal
This document presents a finite element analysis of a crankshaft using ANSYS. A 3D model of the crankshaft is created in Solidworks and meshed in Hyperworks. Static structural analysis is performed in ANSYS for different materials, including structural steel, Inconel x750, and Al6061. Boundary conditions are applied to simulate supports, and pressure is applied to the crankpin. Results such as total deformation, von Mises stress, and shear stress are obtained and compared for the different materials.
Finite element analysis of single cylinder engineLaukik Raut
This paper deals with, the problem occurred in single cylinder engine crank shaft. It consist of static structural
and fatigue analysis of single cylinder engine crank shaft. It identifies and solves the problem by using the
modeling and simulation techniques. The topic was chosen because of increasing interest in higher payloads,
lower weight, higher efficiency and shorter load cycles in crankshaft. The main work was to model the crank
shaft with dimensions and then simulate the crank shaft for static structural and fatigue analysis. The modeling
software used is PRO-E wildfire 4.0 for modeling the crank shaft. The analysis software ANSYS will be used for
structural and fatigue analysis of crank shaft for future work. The material for crank shaft is EN9 and other
alternate materials on which analysis will be done are SAE 1045, SAE 1137, SAE 3140, and Nickel Cast Iron.
The objectives involves modeling and analysis of crank shaft, so as to identify the effect of stresses on crank
shaft, to compare various materials and to provide possible solution.
The document discusses the design optimization and analysis of a propeller shaft using finite element analysis. It aims to replace conventional steel drive shafts with alloy materials to reduce weight. The researchers used AISI 8750 low alloy steel and optimized the design in ANSYS to minimize weight while ensuring sufficient performance under loads. Their analysis estimated deflection, stresses, and natural frequencies of both steel and alloy propeller shafts to compare performance and validate the optimized alloy design.
Design and Thermal Analysis of Disc Brake for Minimizing TemperatureIRJET Journal
This document describes a study on the design and thermal analysis of disc brakes to minimize temperature. Different shapes and slot designs were modeled for a disc brake rotor using CATIA software and thermal analysis was performed using ANSYS. The results from static structural and transient thermal analysis for the original design and 5 new designs under various loading conditions are presented and compared. The analysis shows that the new design 5 performs the best with maximum stresses and temperature below the original design, indicating improved thermal conductivity and heat dissipation. This optimized design can help improve brake performance and safety.
Design optimization of excavator bucket using Finite Element MethodIjripublishers Ijri
An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations,
such as digging, ground leveling, carrying loads, dumping loads and straight traction. Normally backhoe excavators
are working under worst working conditions. Due to severe working conditions, excavator parts are subjected to
high loads and must work reliably under unpredictable working conditions. Thus, it is necessary for the designers to
provide not only an equipment of maximum reliability but also of minimum weight and cost, keeping design safe under
all loading conditions.
LOCOMOTIVE WHEEL ASSEMBLY DESIGN OPTIMIZATION USING FINITE ELEMENT ANALYSISIjripublishers Ijri
Underground mining is the regular happening work around the world, mainly in India for coal, iron ore, gypsum
etc…………..
Transportation of the material is the major criteria for underground mining most commonly locomotive trolleys, belt
conveyors (or) screw type conveyors are used to carry the material from underground to surface.
Locomotive trolleys are the most efficient transportation system for underground system even for human transportation
also it can be used.
Now all the mining companies are using belt type (or) screw type conveyors because of regular maintenance (or) replacement
of locomotive trolleys, but screw conveyors and belt type conveyors are making heavily wastage falling from belt
conveyors and crushed wastage from screw conveyor.
This project deals with design optimization for improving the life of locomotive trolley.
3D models will be prepared according to company standards.
FEM based analysis will be conducted on assembly to find the location of maximum stress.
Static and model analysis will be carried out by applying suitable materials and modifying part by observing the above
analysis.
Air Flow Test Bench A Senior Capstone ProjectGina Brown
This document describes a senior capstone project undertaken by mechanical engineering students at Western Kentucky University to design, build, and test an air flow test bench. The test bench was designed to measure airflow resistance of test specimens and performance of air moving devices over a flow range of 10-2000 CFM. It included major components like a variable speed blower, nozzle flow measurement device, housing plenum, flow straighteners, and data acquisition system. The project was funded by ASHRAE and followed standards to characterize performance of air devices and pressure drops for educational use in future mechanical engineering labs.

Rotating valve assembly for high temperature and high pressure operation
United Stated Patent #7,739,867
Kenyon, et al. June 22, 2010
Compact, low pressure-drop shock-driven combustor
Patents (granted)
Description: I led the development of this valve while working on the pulse detonation program at
General Electric’s Global Research laboratory. It is designed to handle the extremely high
mechanical and thermal loading of pulse detonation combustion while functioning in the high-
pressure and high-temperature environment of a gas turbine engine combustor. The success of
this design played a key role in winning a large government contract to continue development of
the technology, and was the cornerstone of GE’s prototype hybrid engine design.
Description: Early in the pulse detonation
research program, we investigated an
exciting method of initiating the
combustion process using shock waves.
The process was known as shock-to-
detonation transition, and it provided
significant advantages over existing,
known processes. This invention drew
upon fundamental shock wave research
and provided successful test results. I led
the design, construction and testing of
this prototype combustor.

Pulse detonation combustor
Variable initiation location system for pulse detonation combustor
Patents (granted)
Description: To integrate
pulse detonation technology
into existing gas turbine
engines, we had to radically
rethink the layout of the
engine. This patent captures
our successful solution to the
most difficult integration
challenge – managing the
unique geometry and ensuing
thermal growth of the pulse
detonation combustor tubes
over the operating envelope
of a gas turbine engine.
Description: A key challenge for the pulse detonation program was maintaining combustor
operability over the wide range of conditions found in the gas turbine engine. We were able to
successfully solve some of these issues by incorporating variable geometry elements in the
combustor.

Most of my work with GE is either proprietary,
export controlled or government classified.
However, this device is cleared for public disclosure
as its design, manufacture and testing was part of my
graduate thesis at The Ohio State University. This is a
mechanical brake used to test frangible driveshafts
for accessory gearbox components of large
commercial turbofan engines. The brake attaches to
the gearbox and applies torque of up to 2000ft-lb at
9000rpm. This torque causes the gearbox shaft to
rupture and the dynamic response of the gearbox is
measured to ensure compliance with FAA
regulations.
I designed the $30k brake to use as many off-the-
shelf components as possible (including standard
automotive brake calipers) and it saved GE $300k
relative to a proposed custom design. I created a
computational model to predict performance, sized
the hydraulic system, performed finite element
analysis, guided a drafter to create detailed
engineering drawings, reviewed the design with
chief engineers, then supported manufacturing. Once
it was assembled, I performed laboratory tests to
ensure it met the design requirements. (2006)

This “Launch and Impact Tester for Aerial
Forestation” was designed and built as a senior
capstone design project at Boston University. I
worked with two fellow students on this project. It
was awarded the “Most Outstanding Capstone
Design Project” for 2004 and it was later featured on
Discovery Channel’s “Ways To Save The Planet”
series which aired in 2008.
It is capable of firing 2lb projectiles into the ground
at speeds of up to 300ft/sec. The projectiles are to be
used for aerial forestation - a process of planting
trees by dropping them from an airplane. We created
computational models to analyze the air flow that
propels the canisters and the dynamics of the valve
opening mechanism then built, tested and calibrated
the device for use. (2004)

The SAE Mini Baja is an intercollegiate event in which
amphibious off-road vehicles are designed, built and raced. I
was the captain of BU’s first ever Mini Baja team; we
designed and built the car during the 2002-2003 school year
and raced in the Mini-Baja East competition, held in April
2003 in Orlando, FL. We sourced major components like the
engine, transmission, shocks, struts and brakes but built the
chassis entirely from scratch. We placed 18th overall in a
field of 50 competitors, including a first place finish in the
Land Maneuverability event, a second place finish in the Mud
Bog event, and a 12th place finish in the four-hour-long
Endurance Race. We developed a novel design for the
fenders that allowed them to pivot with the suspension to
improve propulsion in the water while having the strength
to withstand multiple vehicle rollovers.

This is a PCR (Polymerase Chain Reaction) machine
for which I did the majority of the mechanical design
and packaging while working at Fraunhofer USA. I
worked on the project with a software engineer and
a DNA chemist. One challenge for this project was to
mount an ultraviolet ring light and camera above the
sample tray and keep the system “light tight” while
maintaining adjustability. I solved this problem with
a rubber bellows that is held in place with magnets.
