Cold spray is an emerging technology that shows great promise for the repair of civil aircraft components. However, certification of such repairs requires a comprehensive evaluation of repair performance, including a detailed assessment of repair strength and the associated failure mechanisms. The present …

Biogas production involves the complex process of anaerobic digestion in bioreactors. This paper presents numerical modeling results and analysis of bioreactors. We discuss research methodology, model geometry, internal bioreactor processes, and possible modifications. Two mathematical models and their …

This article presents a Multiscale Modeling Framework for the prediction of the progressive damage and failure analysis of laminated composites structures reinforced with carbon nanotubes (CNTs). First, the modified Halpin-Tsai (H-T) model is employed to estimate the mechanical properties of CNT-reinforced …

Abstract The upcoming EURO 7 regulation requires significant CO2 reductions in road freight, targeting towing vehicles and semitrailers. Semitrailers face a 10% reduction goal, with limited gains from aerodynamic tweaks and low rolling resistance tires, making electrification the most promising solution. …

Fluorescent Penetrant Inspection (FPI) is a widely used inspection technique in the aerospace industry. Because of the aging aerospace sector, and because of the safety-criticality of the inspection, aerospace companies aim to automate (parts of this) inspection process to support inspectors. This paper …

Routine maintenance of commercial aircraft requires reliable detection and repair of corrosion to ensure structural integrity. Post-repair inspections are commonly performed using manual ultrasonic point measurements of residual thickness, a process that is time-intensive and constrained by limitations …

We conducted a descriptive study among first-year engineering students at the Anton de Kom University of Suriname. We analyzed students’ errors regarding necessary prior knowledge in a calculus A exam. We found that the stage of the solution in which prior knowledge is required impacts the importance …

This research examines the impact of transitioning to an autonomous operation on the airside of Schiphol airport, with a specific focus on emissions that affect both the environment and the staff working within airport premises. This study will explore current emissions from vehicles on Schiphol's airside, …

This paper aims to present a comprehensive investigation to obtain the structural calculations needed to design a rigid panel of aluminum alloy for the wing box beam of an ATR 72–500 aircraft. For this design process, several types of materials, including composites like CFRP, are considered so it is …

This study focuses on the feasibility of electric aircraft operations between the Caribbean islands of Aruba, Bonaire, and Curaçao. It explores the technical characteristics of two different future electric aircraft types (i.e., Alice and ES-19) and compares their operational requirements with those …
