Abstract
An aircraft static test adapter assembly comprising a static test head for performing testing at an aircraft static port on an aircraft body. The static test head is biased, and optionally supported by a biasing member extending in use from the static test head to the ground. A biasing mechanism provides a biasing force to the biasing member which is transferred by the biasing member to the static test head such that it is held in place. Abstract not intended to be limiting.
Claims29
An aircraft static test adapter assembly for applying static test equipment to an aircraft static vent comprising:
- a static test head comprising
- a static test opening defined about an axis adapted for communicating with an aircraft static port of an aircraft;
- a conduit opening for connecting to an air conduit providing pressure;
- and
- a sealed air passage defined between the static test opening and the conduit opening;
- a seal in continuous contact with said static test head around said static test opening about said axis, the seal being adapted for pressing against an aircraft body around the aircraft static port to create a sealed passage between the static test opening and the aircraft static port;
- and
- a biasing arm for transmitting a force to the static test head, the biasing arm having a first end and a second end and comprising at a second end a connection for connecting to the static test head and extending longitudinal away from the second end to a first end, the first end comprising a ground contacting portion adapted for resting against a ground surface.
A method for performing a test on an aircraft static port of an aircraft pitot-static system comprising:
- positioning a static test head having a static test opening surrounded by a seal against an aircraft body such that the seal surrounds the aircraft static port;
- positioning a biasing arm having a first end and a second end and connected to the static test head at the second end such that the first end contacts the ground;
- biasing the biasing arm in a direction towards the aircraft body such that a biasing force is transferred to the static test head pressing the static test head against the aircraft body.
An aircraft static test adapter assembly for applying static test equipment to an aircraft static vent comprising:
- a static test head means comprising means for establishing a sealed contact between an air conduit and an aircraft static port on an aircraft body;
- a biasing arm means mountable between a ground-based support to the static test head for transferring a biasing force to the static test head means;
- and
- a biasing means for providing a biasing force to the biasing arm means, the biasing force forcing the biasing arm in a direction toward the aircraft body.
