Abstract: Methods and apparatus to determine airflow conditions at an inlet of an engine are disclosed herein. An example method disclosed herein includes providing a frame having an inner surface and an opening therethrough to define a passageway; and mounting laser sensors to the inner surface of the frame, the laser sensors to measure a characteristic of a fluid that is to flow through the passageway of the frame.

Abstract: Methods and apparatus to determine airflow conditions at an inlet of an engine are disclosed herein. An example apparatus disclosed herein includes a sensor disposed at an inlet of an engine to measure a pressure characteristic, a temperature characteristic and a velocity characteristic of an airflow moving through the inlet and a processor to determine an air mass flow rate based on the pressure characteristic, the temperature characteristic and the velocity characteristic measured at the engine inlet.

Abstract: A method and apparatus are present for processing information. Raw information is received from a sensor network and a number of systems in an aircraft during a test of the aircraft performed during operation of the aircraft. The raw information is placed in a memory and is processed using processes run by a processor unit that accesses the memory to form processed information while new raw information is being received in the memory. The raw information and the processed information are both present in the memory. The raw information and the processed information are stored in a storage system. A determination is made as to whether additional tests are needed for the aircraft using the processed information prior to a conclusion of the operation of the aircraft. At least one of the raw information and the processed information are sent to a remote location using a wireless communications link.
