An aircraft study of rapid precipitation development and electrification in a growing convective cloud

Atmospheric Research, 1994
Abstract The rapid initial precipitation growth and initial electrification of a convective cloud, growing as a new cell on the upshear side of a cloud system in Florida, is traced from radar data and aircraft penetrations at the −7°C to −10°C level.

Powering Commercial Aircraft: The Next Logical Step in Vehicle Electrification [Viewpoint]

IEEE Electrification Magazine, 2017
Reports on programs that have demonstrated the feasibility of electric propulsion for commercial aircraft. power by wire has electrified certain pneumatic and hydraulic loads. This investment is, in turn, driving the rapid development of key component technologies. Several programs in recent years have demonstrated the baseline technical feasibility of

Fuel-based thermal management systems for aircraft electrification: modelling and performance analysis

The Aeronautical Journal
Abstract Recent trends in the context of aircraft propulsion and systems electrification are met with challenges, as new sources of on-board waste heat generation are introduced. The development and optimisation of innovative thermal management systems (TMS) for aviation is a key asset in addressing those challenges.

Autogeneous Electrification of a B-45A Aircraft. Part 1. Preliminary Investigation

1951
Abstract : The problem of precipitation static is becoming increasingly severe with present-day high-speed aircraft. The use of large transparent plastic surfaces with various antenna mounted under the plastic surface accentuates the problem. A B-45A type aircraft was instrumented to measure the electrostatic condition of the aircraft and the canopies ...

Actuation Challenges in the More Electric Aircraft: Overcoming Hurdles in the Electrification of Actuation Systems

IEEE Electrification Magazine, 2017
The last several decades have witnessed an everincreasing drive toward more electric aircraft (MEA). This drive stems from the need to improve efficiency and reduce lifetime operating costs of the aircraft. Recently, work has focused on the all-electric aircraft (AEA) in which everything, including propulsion, is powered by electric machines (Loff 2016,
