Abstract: An inlet particle separator system for a gas turbine engine includes a separator manifold. The separator manifold includes an inlet upstream from an outlet. The inlet is to receive an incoming airflow, and the outlet is to be fluidly coupled to an inlet of the gas turbine engine. The inlet particle separator system includes at least one dry fog nozzle coupled proximate the inlet so as to face at least partially away from the inlet. The dry fog nozzle is external to the separator manifold, and the dry fog nozzle is to direct a spray of dry fog in a direction transverse to the incoming airflow to agglomerate with fine particles in the incoming airflow to form agglomerated particles. The inlet particle separator system includes a scavenging system coupled to the separator manifold downstream from the inlet, and the scavenging system removes the agglomerated particles from the separator manifold.

Abstract: This disclosure is directed to techniques, methods, devices, and systems for generating a bird and bat detection radar output using weather radar. In one example, a method includes generating, by a computing device that comprises one or more processors and is onboard a vehicle, a radar control output for an aircraft weather radar system to generate a radar transmission tuned to detect birds and bats. The method further includes receiving, by the computing device, radar data in response to the radar transmission. The method further includes determining, by the computing device, whether the radar data comprises data indicative of detected birds or bats. The method further includes generating, by the computing device, an output based at least in part on the data indicative of the detected birds or bats.
