Solid-state power controllers (SSPCs) have been received increasing attention as they can configure the electrical system and protect by fast tripping mechanism at same time. Although high-voltage direct current (HVDC) bring sustainable savings on cables' weight losses, protection be considerably challenging. SSPCs successfully utilized for 28V DC aircraft onboard network. However, ones are imp...

The goal of this study is to analyze how the aeropropulsive benefits an over-the-wing distributed-propulsion (OTWDP) system at component level translate into benefit aircraft level, as well determine whether enhancement sufficient lead a reduction in overall energy consumption. For this, preliminary sizing partial-turboelectric regional passenger performed, and its performance metrics are compa...

The energy management strategy of a hybrid-electric aircraft is coupled with the design propulsion system itself. A new space exploration methodology based on Set-Based Design introduced to analyse effects different strategies fuel consumption, NOx and take-off mass. Probabilities are used evaluate discard areas not capable satisfying constraints requirements, saving computational time correspo...

INTRODUCTION: Diffusion-weighted MRI (DWI) provides a non-invasive method for in vivo evaluation of tissue water mobility. Most DWI studies employ single-shot EPI techniques which can suffer severe artifacts and image distortion in some applications. Multi-shot FSE-based DW-PROPELLER (1) and Turboprop (2) have shown to overcome these limitations. However, the scan time is usually longer to achi...

This paper deals with the experimental assessment of aerodynamic characteristics an innovative large turboprop aircraft. The configuration is a three-lifting surfaces airplane rear engine installation at tail tips, conceived to carry up 130 passengers and targeting minimum economic environmental impact, which competitive regional jets on short medium hauls. layout output previous research made ...
