Abstract: An image processing apparatus comprises processing circuitry configured to: obtain a respective identity and location for each of a first plurality of landmarks in a reference volume; obtain a respective weighting for each landmark of the first plurality of landmarks; obtain a respective identity and location for each of a second plurality of landmarks in a further volume; and determine a transform based on a fit between the first plurality of landmarks and the second plurality of landmarks, wherein the fit is determined in dependence on the weightings.

Abstract: Provided is a composite joint comprising a pair of composite panels each defining a composite panel thickness and having an inner face sheet and an outer face sheet sandwiching a core panel therebetween. The core panel defines a constant thickness portion and a ramp portion along which the core panel tapers to a reduced thickness portion. The outer face sheet is thickened in the area of the reduced thickness portion. The core panel includes a plurality of cells extending between the inner and outer face sheets. The cells within the reduced thickness portions are filled with a filler material. The cells within the ramp portions and constant thickness portions are filled with aerogel. A primary splice plate extends across the reduced thickness portions. Mechanical fasteners extend through the outer face sheet and into the primary and secondary splice plates. A themal barrier compound covers the primary splice plate.

Abstract: Provided is a composite joint comprising a pair of adjoining composite panels disposed in side-by-side arrangement and being generally aligned with one another. Each one of the composite panels has opposing inner and outer face sheets sandwiching a core panel therebetween and includes a ramp portion wherein the composite panel transitions into a reduced thickness solid laminate edge portion. The core panel includes a plurality of cells extending between the inner and outer face sheets. The cells within the ramp portions are substantially filled with a filler material. The cells adjacent to the ramp portions are substantially filled with aerogel. The composite joint further comprises a primary splice plate extending across the solid laminate edge portions of the adjoining composite panels with mechanical fasteners extending through the solid laminate edge portions and passing through the primary splice plate. A layer of thermal barrier compound covers the primary splice plate.

Abstract: An aircraft motion control mechanism for regulating aircraft motion from a location remote from an aircraft body portion. The aircraft auxiliary control mechanism has at least one control surface support arm connected to and extending from the aircraft body portion, and an auxiliary flow control surface connected to the support arm. By pivotally controlling the movement of the support arm, the auxiliary flow control surface is operative to deflect airflow to regulate orientation of the aircraft. In addition, the auxiliary flow control surface may further deflect the airflow by deflecting about the support arm.
