Modeling And Parametric Performance Analysis Of Field Emission Electric Propulsion

de Dinaol Gadisa

41,45€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Master's Thesis from the year 2023 in the subject Engineering - Aerospace Technology, grade: 3,4, , language: English, abstract: Space electric propulsion is required not only for orbit raising and transfer, position control, and station keeping, but also for spacecraft attitude control, advanced thermal material testing, and end-of-life de-orbiting that is much more fuel efficient than conventional chemical rockets. FEEP thruster is one type of ion propulsion system that provides a low thrust of the order of micro-Newton (uN) to milli-Newton (mN) that is primarily used for precise spacecraft attitude control with extremely high efficiency and small impulse bits based on the exhaust velocity of an ejected ion from a thruster. This thesis report includes a mathematical and 3D CAD model of a FEEP thruster with the overarching goal of investigating and analyzing the thruster s parametric performance. To accomplish this, a MATLAB program was used to simulate the change in thrust and exhaust velocity over time using various types of liquid metal as a propellant, assuming the fuel mass is equal to the atomic mass of the propellant, the wet mass of the spacecraft is assumed to be 4kg, and the charge of an ion is assumed to be 1.602 10-19 while the supplied voltage is held constant at 10 kV. Furthermore, because the porous crown emitter is the heart of the FEEP thruster, its stiffness and topology optimization were investigated. The simulation results show that the thrust value of the FEEP thruster over time ranges from 0.213 N to 211mN during stable ion flow rate and mass expulsion of indium propellant, implying that the result is comparable to realistic FEEP parameters. Furthermore, as expected, increasing the voltage between the emitter and extractor electrodes and decreasing the mass expulsion of the propellant increased the thrust value of the FEEP thruster.

Analyzing Aircraft Reliability With The Application Of Weibull Distribution Theory

de Holger Jedemann

1,31€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Diploma Thesis from the year 1992 in the subject Engineering - Aerospace Technology, grade: 95, , language: English, abstract: Determining an aircraft component's reliability often involves estimating its mean life, although to do this, the appropriate statistical distribution must be applied. The exponential model is often used because of its simple application. However, this distribution has its limitations. To overcome the shortcomings of the exponential model, this thesis examines how Weibull Distribution Theory can be utilized to produce appropriate component reliability estimators with a degree of certainty. The Weibull distribution is a flexible distribution in that it has the ability to approximate other distributions such as "Normal" and "Exponential . Subsequently, appropriate mean life estimators can be determined for various types of life data. The versatility offered by the Weibull Distribution model makes it ideal for selectively supplementing current methods of field reliability monitoring, especially when the onset of component wear out is suspected or the success of a modification is sought. The type of field data encountered when monitoring aircraft reliability dictated that a Weibull model be developed for Type 1, multiply censored data. To determine whether data fitted a Weibull distribution, the Rank Regression method was used to produce median ranks for plotting on Weibull probability paper. To analytically determine Weibull parameter estimators and approximate confidence limits, the Maximum Likelihood method was utilized. Automation of both these methods was achieved using Fortran programming. As the number of failures increase, Weibull parameters stabilize and the degree of certainty provided by Weibull confidence limits improves. This results in the Weibull model being able to produce mean life estimates in a timely manner. With the aid of Weibull shape parameters, field problems may be relatively quickly identified and/or confirmed, allowing for faster corrective action response.

DISPONIBILIDADE IMEDIATA

 Academic Paper from the year 2021 in the subject Engineering - Aerospace Technology, grade: A, , course: Aerospace Technology II, language: English, abstract: Wind tunnels are a great way of obtaining precise and accurate data on an aerofoil or model aircraft. They are crucial because they help engineers save a lot on resources; rather than having to make a full prototype by "winging it", as they say, with a wind tunnel, it is possible to test a collection of low-cost models prior to the prototyping stage in order to find the best configuration for a design. As such, this assignment will cover the operation of wind tunnels from multiple points of view, looking at the various uses of a wind tunnel both from theoretical and practical points of view.
