Abstract Hybrid-electric power is an appealing technology for multirotor platforms due to its ability enhance the range of vehicle while providing low emissions and precise thrust control required stability. The development a utilizing hybrid propulsion essential step CfAR as it will be basis research on this in flight. designed multirotor, MIMIQ (Modular Inertia Matching Quadcopter), 32kg quadcopter with motor-to-motor diameter 2.7m which require total 3,700W hover. This demand primarily...
Lattice structures are becoming an increasingly attractive design approach for the most diverse engineering applications. This increase in popularity is mainly due to their high specific strength and stiffness, considerable heat dissipation, relatively light weight, among many other advantages. Additive manufacturing techniques have made it possible achieve greater flexibility resolution, enabling more complex better-performing lattice structures. Unrestricted material unit cell designs...
A new method for the synthesis of structures with prescribed target natural frequencies and mode shapes is presented. The introduction a modal Rayleigh quotient approximation based on means to propose structural problem whose solution free from eigenvector sensitivity analysis. can be adjusted as close possible desired values, while minimizing total mass. Several examples corroborate efficacy proposed method.
This paper presents a methodology for constructing an aero-propulsive system identification model fixed-wing propeller-driven aircraft with limited flight data. Developing dynamics is iterative process involving costly and time-consuming testing to collect relevant To maximize the utilization of available data, this study employs time-domain procedure on data from various maneuvers flights.

This article is focused on the development and characterization of highly controllable magnetorheological materials for stiffness damping control in semi-active applications. Two types are developed in-house: elastomer with soft base elastomer, fluid encapsulated regular namely fluid-elastomer. In both cases elastomers fluid-elastomers, samples evaluated using in-house-developed shear compression test rigs, which equipped electromagnets Hall effect sensors measuring magnetic field. These...

The dawn of research on shock and boundary layer interaction control dates back to the 1970s, when humped transonic aerofoils were first studied as a means improve performance supercritical aerofoil technology at off-design conditions. Since then, bumps have been found be promising devices for such kind flow control. They smearing effect wave structure achieved through isentropic pre-compression upstream main can significantly lower drag without incurring unacceptable viscous losses....
The aeronautical industry is currently facing the simultaneous and conflicting demand to enhance flight efficiency while reducing emissions. One potential solution for fuel consumption increase wing aspect-ratio as it improves lift-to-drag ratio. However, higher wings result in deflections which turn may lead non-linear aeroelastic behaviour. In this work, behaviour of a conventional regional aircraft with high investigated. structural design aims ensure that able withstand load limit 3.8g....
