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...

Abstract. During each voyage, the vessel's traction capacity decreases due to the gradual degradation of the characteristics of the propulsion complex. This process is influenced by factors such as fouling of the vessel'...

Polymeric composites have been widely used in various structural and thermal aerospace applications. Polymeric composites having high strength and high modulus reinforcement are ideally suited for lot of critical aerospa...

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...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

Widespread attention has been drawn to the underwater biomimetic robotic fish due to its excellent agility and little environmental disturbance. A hybrid-driven bionic robotic fish outfitted with dual-propeller thrusters...

AUVs have essential applications in oceanic investigations, environmental characterization, and subsea surveys where accuracy in positioning and stability for navigation is challenging. AUV proposed in the present work a...

In recent decades, alternative propulsion systems have been investigated and have attracted great interest in the space community. Most of these alternative propulsion systems need propellants. One alternative propulsion...

Excessive armature mass fraction in asynchronous induction coil thrusters critically constrains payload capacity and propulsion efficiency. This study addresses this limitation through two lightweight strategies: axial h...

In this paper it is presented the concept and design of a new type of spacecraft that could be used to make the first manned interstellar travel. Solar one would integrate three near-term technologies, namely: compact nu...

Microwave ignition (MWI) technology enables synchronized large-area multi-point ignition, multi-pulse operation, higher combustion temperature and efficiency, and dynamic thrust modulation through microwave field adjustm...
