The purpose of this article is to investigate utilization of common-rail turbocharged diesel aero-engines as primary propulsion powerplant for light-to-medium helicopters and airplanes. This article summarizes the result...

This research introduces a hybrid modeling framework that combines intricate combustion dynamics with machine learning (ML) to facilitate the decarbonization and retrofitting of traditional diesel engines utilizing Hydro...

With the increasingly stringent environmental regulations on road traffic, the emission standards for particulate matter from internal combustion engines have risen significantly. Consequently, the implementation of part...

This study investigates two NOx-mitigation strategies, namely exhaust gas recirculation (EGR) and water–diesel emulsification, in a diesel–hydrogen dual-fuel compression ignition engine. A validated three-dimensional...

Abstract The paper presents a method of calculating the full load engine characteristics based on the Leiderman–Khlystov relation. Because the values of the coefficients of the discussed function available in literatur...

No commercial airplane in service today is able to fly half great-circle distances over the globe and achieve the non-stop or the global range to any antipodal location on Earth. A subsonic jetliner has the optimum cruis...

Electro-optic modulation is a key function in optical data communication and possible future optical compute engines. The performance of modulators intricately depends on the interaction between the actively modulated ma...

Aircrafts are one of the most important means of transportation today. For aircrafts to be able to serve safely, their maintenance must be done in a timely and complete manner. In addition to regular maintenance, it may ...

Comfort is an important factor for passengers in the selection of airlines, and electric propeller aircraft will be an important element of future sustainable aviation. In this paper, we studied the order of importance o...

Abstract Targeting the environment of gas-cooled reactors (800 °C, 1 Mpa), we propose an all-sapphire composite-cavity sensor system for pressure measurement with in-situ temperature compensation. The sensor based on ...

Abstract Selective Catalytic Reduction (SCR) helps to reduce Nitrogen Oxide (NO) emissions from diesel engines using catalytic materials made of thermally stable non-precious metals. A dual support SCR catalyst using iro...

Abstract The current research of titanium alloy on friction welding process in the field of aero-engines mainly focuses on the linear friction welding. Compared to the linear friction welding, inertial friction welding o...

Efforts to conserve fuel oil (BBM) promoted by the Indonesian government and many other countries are motivated by the fact that fossil fuel availability has decreased and environmental pollution continues to worsen. Str...

This research paper focuses on the optimization of the propulsion system of a blended wing body design. Two different aspects of the design, the engine placement and count, and the engine itself, are investigated. The pr...

A sustainable urban economy seeks to strike a balance between economic growth, social justice, and environmental protection in cities. This concept focuses on the optimal use of resources, reducing environmental impacts,...

This study explores the potential of cultural tourism as a strategic driver for sustainable urban development in Hail City, Saudi Arabia, emphasizing its alignment with the objectives of Saudi Vision (2030). Situated at ...

Abstract Engine tests are both costly and time consuming in developing a new internal combustion engine. Therefore, it is of great importance to predict engine characteristics with high accuracy using artificial intellig...

Abstract The shift from internal combustion engines to electric powertrains has redefined the noise, vibration, and harshness (NVH) profile of contemporary vehicles. The reduction of engine-generated broadband noise has ...

Electric vehicles are currently the leading solution in the automotive market to reduce greenhouse gas emissions. However, transitioning from traditional internal combustion engines poses many challenges. One of these ch...

Abstract: During the last years, several thrust control systems of aerospace rocket engines have been developed. The fluidic thrust vectoring is one of them; it is simple in design and offers a substantial gain in weigh...

The ability to see simultaneously with both eyes working together is known as binocular single vision. A healthy anatomical, motor, and sensory system is necessary for single binocular vision. Thus, binocular vision anom...

A conceptual and feasibility study of an RBCC SSTO catapult-launched reusable strap-on parallel-boosted gliding-reentry lifting-body spaceplane for economic manned short-duration 300-kg payload LEO access is presented an...
