Abstract: A rotorcraft has a fuselage, an engine disposed substantially laterally centrally relative to the fuselage, and an air intake system (AIS). The AIS has a first duct configured to provide streamline air flow, a second duct configured to provide streamline air flow, and a combining section configured to receive streamline air flow from each of the first duct and the second duct. The combining section is further configured to output streamline air flow.

Abstract: A system and method for reducing data noise for vehicle monitoring sensors using parameter-based correction. The system includes a sensor operable to make a sensor reading and generate a sensor signal, and a data server operable to acquire a condition indicator model correlating operational parameters with condition indicators, and to acquire a current condition indicator according to the sensor signal, the data server further operable to generate an adjusted condition indicator by adjusting the current condition indicator according to the condition indicator model, and to determine whether an alert condition is indicated, according to at least the adjusted condition indicator, by a condition indicator set that includes the adjusted condition indicator, and to provide an alert in response to determining that the alert condition is indicated.

Abstract: An aircraft is described with both VTOL (vertical takeoff and landing) capabilities and convention airplane capabilities. A preferred embodiment comprises a fuselage and fixed wing, with one boom on either side of the fuselage. Each boom comprises a tilt rotor on a fore end and a fixed rotor on the aft end. Both rotors can be directed vertically for VTOL capability. During cruise the tilt rotors can be directed forward for thrust and the fixed rotors can be stopped and directed along the boom axis, minimizing drag. The described embodiments have advantages in weight savings and maneuverability compared to other VTOL aircraft.
