Available in PDF, EPUB and Kindle. Book excerpt: Durability test has been increasingly important due to demand for the extended life of the vehicles and hence vehicle’s powertrain. When these long, time-consuming durability tests are running, there is a need for automated checks to assess if they are running as per the requirement. This requires us to know acceptable error range for each of the measured variables and performance parameters. Hence, the main objective is to find the exhaustive error band of the system’s important performance parameters through measured variables. A detailed uncertainty analysis, consisting of systematic and random uncertainty is calculated for performance parameters like Brake Mean Effective Pressure (BMEP), Brake Specific Fuel Consumption (BSFC), Air-Fuel Ratio (AFR), Indicative Mean Effective Pressure (IMEP) and air flow rate into the engine. The uncertainty in the performance parameters is calculated from the uncertainty of the measured variables. The effect of the environmental conditions like air temperature, humidity, and variation of part-to-part are also taken into consideration for calculating the uncertainty. The systematic uncertainty is calculated by the understanding of the system, i.e. the sensors and the actuators of the engine cell, while the random uncertainty is calculated using the data from GT-Power model simulations. Student’s t-distribution is used to calculate the uncertainty as for the true value of the mean and standard deviation of the data received is not known. Error bounds of the performance parameters are found using the GT-Power simulations. A list of performance parameters with the major contributing factors to their uncertainties is listed. Root cause analysis of the performance parameter is shown at the end of the literature.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. Correlations of engine test facilities is required to ensure that the effects of the engine test facility are accounted for in the performance testing of the engine under test. This will ensure that operators are getting good performance measurement of the engines tested in the facility.This document describes a recommended practice and procedure for the correlation of Turboshaft/Turboprop engine test cells. Correlation of the facility results in the establishment of the required correction factor for the facility and specific engines to be tested.

Download or read book Uncertainty Quantification in Computational Fluid Dynamics and Aircraft Engines written by Francesco Montomoli and published by Springer. This book was released on 2018-06-21 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces design techniques developed to increase the safety of aircraft engines, and demonstrates how the application of stochastic methods can overcome problems in the accurate prediction of engine lift caused by manufacturing error. This in turn addresses the issue of achieving required safety margins when hampered by limits in current design and manufacturing methods. The authors show that avoiding the potential catastrophe generated by the failure of an aircraft engine relies on the prediction of the correct behaviour of microscopic imperfections. This book shows how to quantify the possibility of such failure, and that it is possible to design components that are inherently less risky and more reliable. This new, updated and significantly expanded edition gives an introduction to engine reliability and safety to contextualise this important issue, evaluates newly-proposed methods for uncertainty quantification as applied to jet engines. Uncertainty Quantification in Computational Fluid Dynamics and Aircraft Engines will be of use to gas turbine manufacturers and designers as well as CFD practitioners, specialists and researchers. Graduate and final year undergraduate students in aerospace or mathematical engineering may also find it of interest.
