Jam-tolerant actuator

Abstract: An jam-tolerant actuator (2), comprises a housing (4), a first prime mover (6) for producing rotary motion, a first gearbox (10) arranged to convert in use the rotary motion from the first prime mover (6) into rotary motion. The first gearbox comprises a casing (14) mounted for rotation relative to the housing (4) of the actuator (2) and a second gearbox (16) arranged to convert rotary motion of the casing (14) of the first gearbox (10) into rotary motion. A brake (20) is arranged to act on the rotary motion from the second gearbox (16). In use when the first gearbox (10) is not jammed, the brake is applied to resist relative rotation between the casing of the first gearbox (10) and the housing (4) of the actuator (2). When the first gearbox (10) is jammed, the brake (20) is released thereby allowing the casing (14) of the first gearbox to rotate relative to the housing (4) of the actuator (2). A second motor (22) may also be provided.

In-Flight Broadband Connectivity: Architectures and Business Models for High Capacity Air-to-Ground Communications

Abstract: In-Flight Broadband Connectivity (IFBC) is a significant open market for mobile network operators, considering that more than 3.3 billion passengers were served by airlines in 2015. On-board broadband services are provided via air-to-ground (A2G) connectivity through direct A2G communication (DA2GC) and satellite A2G communication (SA2GC). Available on-board connectivity systems have significant limitations: high latency in SA2GC and low capacity in DA2GC. The customer expectancy is multi-Mb/s connections in every seat, which leads to capacity requirements of Gb/s to the aircraft. Creation of high capacity IFBC requires a collaborative interaction between different industry partners. For this reason, we investigate A2G architectures in terms of economic and technical perspectives, and propose business models by identifying new roles and positioning them in the A2G business ecosystem. In addition, we provide an extensive summary of the state-of-the-art and future improvements for A2G communications.
