An aircraft trolley retention device may include a retention latch with a shaft including a first component of an interlocking assembly and a sleeve including a second component of the interlocking assembly and configured to receive the shaft, and an interlocking assembly. The retention latch may be configured to actuate between a closed position and an open position. The interlocking assembly may be configured to guide the retention latch during the actuation between the closed position and the open position. The retention latch may be configured to retain an aircraft trolley within an aircraft trolley bay when the retention latch is in the closed position. A portion of the retention latch may be configured to be positioned in front of a striker plate corresponding to a handle of an aircraft trolley bay door of the aircraft trolley bay when the retention latch is in the open position.

A system for stock management for on-board catering for a vehicle, in particular for an aircraft, includes a galley which is provided with a control unit for controlling the galley, wherein the control unit is designed to make available stock management data of the galley; a service unit for transporting supplies within the vehicle, wherein the stock management data comprise a stock record of the supplies transported with the service unit; and at least one operator control element which is communicatively connected to the control unit of the galley via a wireless data connection and is designed to record removal of a supply item from the service unit and/or reception of a supply item into the service unit, and to bring about updating of the stock record of the transported supplies on the basis thereof.

A flatpack air chiller device is disclosed. In embodiments, the air chiller device includes a primary chiller or pre-chiller subsystem and a secondary or main chiller subsystem within a housing. The pre-chiller subsystem receives and chills ambient air via cold-side contact with a primary thermoelectric device and directs the pre-chilled ambient airstream to the hot side of a secondary thermoelectric device. The secondary or main chiller subsystem is connected to a recirculating air stream, e.g., circulating through the interior airspaces, compartments, or bays of a galley structure. The pre-chilled ambient airstream absorbs heat from the secondary hot side to progressively chill the recirculating air stream, which is in contact with the cold side of the secondary thermoelectric device before recirculation back into the galley structure interior.

A system includes three switches each having a single pole and dual throws. The respective single pole is on a supply side of the each respective switch. The dual throws are on a load side of each respective switch, and include a respective normally open (NO) throw and a respective normally closed (NC) throw. A first voltage detector is connected from the single pole of the first switch to the NC throw of the third switch. A second voltage detector is connected from the single pole of the second switch to the NC throw of the first switch. A third voltage detector is connected from the single pole of the third switch to a NC throw of the second switch.

An aircraft galley chiller is adapted to fit within a service column of the aircraft. The condenser is elongated, oriented vertically, and includes a bank of fans to increase airflow. The evaporator is also elongated and includes a bank of fans. The evaporator and condenser are oriented with the same plane to produce a footprint that fits within the service column. The evaporator includes a heater element to periodically heat and de-ice the evaporator.

An ultra light weight aircraft composite galley architecture system and method comprises composite construction of a partially molded aircraft monument structure based on embedded load bearing hoops and beams used in conjunction with pre formed composite flat panel construction. An upper L shaped structural section mates with a lower inverted L shaped structural section forming a structure upon which additional panels are joined to form the complete composite galley. This system and method of construction produces a high strength aircraft monument capable of maintaining aircraft structural flight and crash load requirements without external monument extrusions for support. This galley architecture system and method of construction creates an aircraft monument with desirable reduction in weight with no loss of required structural strength.
