Effect of forward motion on engine noise [PDF]
Methods used to determine a procedure for correcting static engine data for the effects of forward motion are described. Data were analyzed from airplane flyover and static-engine tests with a JT8D-109 low-bypass-ratio turbofan engine installed on a DC-9-

Various Methods of Encapsulation Biomaterials in Self‐Healing Concrete: A Review
Engineering Reports, Volume 7, Issue 9, September 2025.Investigation of the different methods of encapsulation of healing materials. ABSTRACT Concrete is known for its inherent vulnerability to cracking, which can be attributed to factors like temperature fluctuations, changes in moisture levels, and cyclic loading.

A generalized computer code for developing dynamic gas turbine engine models (DIGTEM) [PDF]
This paper describes DIGTEM (digital turbofan engine model), a computer program that simulates two spool, two stream (turbofan) engines. DIGTEM was developed to support the development of a real time multiprocessor based engine simulator being designed ...

Engineering Reports, Volume 7, Issue 9, September 2025.This study models MHD flow of Brinkman‐type EO‐based MoS2 nanofluid over a rotatory disk with Hall current, cross‐diffusion, and reactive transport. Numerical results reveal the effects of key parameters on flow, heat, and mass transfer in porous rotating systems.

Investigation of the stall-induced shock wave (hammershock) at the inlet to the engine [PDF]
The peak static pressures measured at the inlet to the engine during stall are presented for a turbojet and two turbofan engines. It is shown for one turbofan and the turbojet that the static pressure ratio across the hammershock does not exceed ...
