Various aspects of specific thrust in ramjet propulsion have been considered. It is shownthat while the peak specific impulse of ideal ramjet is theoretically obtained for fuel/air ratiof 0, the specific thrust which determines the thrust level of a given... see more

The object of research is the working process of the afterburner of the combustion chamber of a turbojet dual-circuit engine with flow mixing. The research was aimed at developing a comprehensive methodology for calculating the afterburner-output device o... see more

Expander bleed cycles have a rather simple configuration when compared to other engine cycles, making them appealing when a new low-thrust engine must be designed. This type of cycles can only operate with light fuels (H2, CH4, C3H8) that can be pumped in... see more

In a quest to reduce fuel consumption and emissions of automotive combustion engines, friction losses from many different sources need to be minimized. For modern designs of turbochargers commonly used in the automotive industry, reduction of friction los... see more

Combustion instability in rocket engines is accompanied by large-amplitude pressure fluctuations in the combustion chamber and (or) intense vibration of the load-bearing structural elements. Unstable operation leads to a decrease in thrust, specific impul... see more

Unlike in the case of high Reynolds number airfoil, selecting a turbulent closure model for the low Reynolds number airfoil is still a challenge. A turbulent model used for high Reynolds number airfoil is not necessarily suitable for low Reynolds number a... see more

Kerusakan engine sulit untuk diprediksi apalagi terkait dengan umur dari komponen mesin. Analisis kerusakan pada engine dapat dilakukan berdasarkan oli dilihat dari tren tingkat keausan, memprediksi kemungkinan komponen yang mengalami kerusakan pada engin... see more
