    Abstract: A method of manufacturing a composite sandwich structure. The method may include individually providing a plurality of planar materials to form a stack. The plurality of planar materials may be free from physical interconnection from each other, and at least one of the plurality of planar materials may include one or more substantially continuous fiber layer as a constituent material of a plurality of constituent materials of the composite sandwich structure. The method may further include simultaneously applying heat and compression to the stack between a male mold and a female mold to form the composite sandwich structure.

    Abstract: A seat-back (100) for a passenger seat. The seat-back (100) may include a core framework (110) having a backing frame layer (120) and a back-rest boundary frame structure (130) connected to the backing frame layer (120). The seat-back (100) may further include a flexible cover (150) which may be fitted over the core framework (110) and which may be configured to substantially enclose the core framework (110), such that a back-rest portion (152) of the flexible cover (150) may be suspended across the back-rest boundary frame structure (130) and a backing portion (154) of the flexible cover (150) may be extended over the backing frame layer (120), so as to tension the back-rest portion (152) of the flexible cover (150) across the back-rest boundary frame structure (130) for supporting and cushioning a back of a user received on the back-rest portion (152) of the flexible cover (150).

    Abstract: An aerial vehicle including a first wing structure and a second wing structure which intersects the first wing structure perpendicularly at a position offset from a midpoint of a transverse axis of the first wing structure in a direction towards a first wingtip of the first wing structure. The aerial vehicle may further include a first set of at least two propellers with respective propeller rotational axes disposed side-by-side along a portion of the first wing structure extending between the midpoint of the transverse axis of the first wing structure and a second wingtip of the first wing structure. The aerial vehicle may further include a second set of at least two propellers with respective propeller rotational axes disposed side-by-side along a first portion of the second wing structure extending from a first surface of the first wing structure. The aerial vehicle may further include a third set of at least two propellers with respective propeller rotational axes disposed side-by-side along a second portion of the second wing structure extending from a second surface of the first wing structure.

    Abstract: An accessible lavatory unit (103) for an aircraft cabin (102) is disclosed. The lavatory unit (103) is configurable between an able-bodied configuration and a PRM-accessible configuration. In the able-bodied configuration the lavatory unit has a first internal floor space (132) and there is a cabin floor space (130) external to the lavatory unit (103). The lavatory unit (103) is expandable into the PRM-accessible configuration in which the lavatory unit (103) is expanded to have a second internal floor space (132), the second internal floor space (132) encompassing a region of the cabin floor space (130). A sink for an aircraft lavatory unit is also disclosed.

    Abstract: A method and system for generating a set of values for respective ones of a set of parameters used in determining rotor blade profiles for a corotating coaxial rotor system. The method comprises establishing a ratio of respective desired thrusts of an upper rotor and a lower rotor of the corotating coaxial rotor system based on a desired performance of the corotating coaxial rotor system; and determining the set of values of the set of parameters from the desired thrusts ratio based on an equal rotation speed condition between the upper rotor and the lower rotor of the corotating coaxial rotor system, wherein the set of parameters includes torques of the upper rotor and the lower rotor.
