摘要： An aircraft lifting assembly includes a jack, a load cell, and a jack adapter. The jack includes an extendable arm having a distal end portion for exerting a force to lift an object. The distal end portion defines a cavity. The jack adapter couples the extendable arm to the load cell and includes a base portion, a cradle portion, and a projection. The base portion defines a jack arm support surface and a load cell support surface. The jack arm support surface opposes the distal end portion of the extendable arm and the load cell support surface opposes the load cell. The cradle portion extends from the base portion to circumscribe a portion of the load cell to secure the jack adapter to the load cell. The projection extends from the base portion into the cavity to secure the jack adapter to the extendable arm of the jack.

摘要： Systems, computer-implemented methods and/or computer program products that facilitate measuring weight and balance and optimizing center of gravity are provided. In one embodiment, a system 100 utilizes a processor 106 that executes computer implemented components stored in a memory 104. A compression component 108 calculates compression of landing gear struts based on height above ground of an aircraft. A gravity component 110 determines center of gravity based on differential compression of the landing gear struts. An optimization component 112 automatically optimizes the center of gravity to a rear limit of a center of gravity margin.

摘要： An aircraft operation method of providing weight and center of gravity information is used to dispatch the aircraft. The aircraft has telescoping landing gear struts and strut seals that interfere with the free movement of the strut. An event trigger signaling departure is detected from aircraft operations at a loading area. Internal strut pressure is measured and recorded upon detection for a period of time as the aircraft moves away. The recorded pressure measurements are transmitted to a first off-aircraft computer, which determines the total weight and center of gravity of the aircraft and provides the information to an operator of the aircraft.

摘要： A method of establishing a justification basis to Aircraft Regulatory Authorities, to allow a regulated aircraft to operate at increased maximum weight limitations, through the statistical identification of non-recognized weight errors being allowed in today's aircraft weight determination methods, with the recovery and utilization of the non-recognized weight errors to increase weight limitations through a Regulatory Authority finding of an Equivalent Level of Safety. A system for use in measuring aircraft weight and center of gravity, providing a method to reveal non-recognized weight errors. Sensors are attached to the landing gear struts, so to periodically and randomly measure and monitor aircraft weight and center of gravity.

摘要： A method for determining the mass of a body is described. The method comprises the application and measurement of a first motive force to the body to move the body in a first state of motion. The acceleration of the body is also measured at this time. This methodology is repeated for a second state of motion. The measured motive forces and accelerations are then used to calculate the mass, and hence the weight of the body. An accelerometer may be employed to measure the accelerations. The methods may be adapted so as to correct for the angle θ of the ground across which the body is moved and or the tilt angle α of the accelerometer relative to the ground. The methods may employ a novel surface angle measuring device that does not require contact with the ground and which does not require the body to be stationary.

摘要： An aircraft undercarriage has an axle for carrying at least one wheel. The undercarriage further includes a magnetic measurement target and at least one magnetic movement sensor cooperating with the magnetic measurement target to measure bending of the axle. The magnetic measurement target has a body that extends inside the axle and includes a fastener end fastened to one end of the axle. The body also include a target surface that extends over an inside surface of the body. The magnetic movement sensor is positioned inside the axle to measure movement of the target surface.

摘要： In a particular implementation, a method includes generating an initial weight estimate associated with an aircraft based on a reference operational empty weight (OEW) and at least one of a latitude or an altitude of the aircraft at a first location. The reference OEW is predetermined at a second location that is distinct from the first location. The method includes determining an additional load capability of the aircraft based on a difference between the initial weight estimate and the reference OEW. The method further includes generating an output that indicates the additional load capability.

摘要： A method for validating or invalidating the computed weight of an aircraft, where the computed weight of the aircraft is determined by compiling various weight assumptions added to a known empty weight of the aircraft. The method measures the aircraft center of gravity, determines the percentage of computed weight supported by the combined main landing gear struts, and using a database such as a look-up table to validate if the percentage of computed weight is determined within a reasonable range to the measured load on the combined main landing gear struts. Sensors are attached to the landing gear struts, so to measure and monitor aircraft loads and center of gravity without measuring the aircraft weight.

摘要： This disclosure describes a system and method for determining the center of gravity of a payload engaged by an automated aerial vehicle and adjusting components of the automated aerial vehicle and/or the engagement location with the payload so that the center of gravity of the payload is within a defined position with respect to the center of gravity of the automated aerial vehicle. Adjusting the center of gravity to be within a defined position improves the efficiency, maneuverability and safety of the automated aerial vehicle. In some implementations, the stability of the payload may also be determined to ensure that the center of gravity does not change or shift during transport due to movement of an item of the payload.
