Centrifugal Compressor and Bell mouth Air Intake Preliminary Design for Micro Turbojet Engine

Journal of Karary University for Engineering and Science, 2021
This paper presents a design of centrifugal compressor and air intake for micro turbojet engine of 200 N thrust. Because of the small size of the micro turbine engines the air intake is designed in the form of bellmouth air intake in order to capture the needed amount of mass flow rate (0.45 kg/s).

(INVESTIGATION OF A MICRO TURBOJET ENGINE VIA REVERSEENGINEERING)

2016
Tersine mühendislik bir aygıt, nesne veya sistemin teknolojik çalışma prensiplerini keşfetme sürecidir. Bu çalışma, özellikle bir mikro turbojet motorun ters mühendisliği üzerine odaklanmaktadır. İlk olarak, gaz türbin motorunun bileşenleri üç eksenli bir optik tarayıcı kullanılarak taranmış ve dijital nokta bulutu formatına dönüştürülmüştür.

Linear mathematical model of single-spool micro turbojet engine with fixed exhaust nozzle

2018 IEEE 16th World Symposium on Applied Machine Intelligence and Informatics (SAMI), 2018
Main goal of this paper is to develop a linear state space representation of a micro turbojet engine based on physical laws describing the operation of the power plant. The importance of micro turbine engines is constantly rising; therefore it is essential to improve their reliability through advanced control systems.

Flow physics in a micro turbojet engine inter-shaft fuel supply system

Physics of Fluids
Inter-shaft fuel supply systems (ISFSSs) consisting of a shaft annulus and a fuel slinger are usually used in micro turbojet engines to pump the fuel to the combustor, aiming at reducing engine's size and weight. Differing from the configuration with stationary fuel pipework, the fast-rotating shaft in the annulus would induce significant drag ...

Vibration Analysis of a Micro Turbojet Engine under Two Impeller Structural Faults

Proceedings of Global Power & Propulsion Society
Disk fracture and locking nut loosening of centrifugal impeller leads to severe vibration of micro turbojet engines, posing significant threats to engine stability and safety. In order to identify the engine vibration characteristics induced by the above two faults in a practical micro aero-engine, vibration acceleration of the engine casing is ...
