UTC Fall 2015 Flight Testing, Support Agency - UTC Aerospace System
United Technologies Corporation (UTC) Aerospace Systems continued flight testing on the Citation Research Aircraft in 2015. Two prototype Optical Ice Detector (OID) instruments are being tested during 10 hours of flights in a variety of cloud conditions. Clouds with only water drops, only ice particles and mixed water/ice clouds are targeted. The Citation Research Aircraft carries advance microphysical instruments for sampling from the surface to an altitude of 40,000 ft. The OIDs performance is evaluated by comparisons with the advanced research instruments on-board the Citation Research Aircraft. The overall goal of UTC's testing program is to have reliable instruments for deployment on commercial airline aircraft.
UTC Fall 2014 Flight Testing, Support Agency -- UTC Aerospace System
United Technologies Corporation (UTC) Aerospace Systems funded a Citation Research Aircraft project to test several instruments under development for commercial aircraft. Instrument prototypes were tested in clouds and precipitation from the surface up to 38,000 ft. The project's objective was to evaluate the prototype instrument's performance by comparing measurements to the Citation's set of research instruments.
Ophir: 2013 - Optical Air Data System Testing, Supporting Agency -- Ophir Corporation
Ophir Corporation is developing an instrument that uses laser returns from aerosols and gases in the atmosphere to characterize the air flow around an aircraft. The University of North Dakota Citation Research Aircraft is test flying the instrument over a range of conditions during dedicated flights.
UTC/Goodrich: 2010-2012 - Optical Icing Detector Instrument Testing, Supporting Agency - UTC Aerospace Systems
United Technologies (previously Goodrich Aerospace Coporations) is developing the Optical Icing Conditions Detector (OICD). The OICD is a lidar-based system for the characterization of the flight environment in terms of airframe icing conditions. A prototype OICD has been mounted on the Citation to test the OICD over a targeted range of conditions in a series of dedicated Citation flights.
SNOwD UNDER: 2010 - Student Nowcasting and Observation with DOW at UND: Educations through Research, Supporting Agency-National Science Foundation
SNOwD UNDER made observations from two polarmetric radars and the University of North Dakota Citation Research Aircraft during November 2010 snow events near Grand Forks, North Dakota. An objective of the project was to identify hydrometeor classification equation sets that work for specific radar wavelengths and to verify those solutions using in situ measurements of snow particles during a regional snow event.
The 20-21 November 2010 snow event near Grand Forks, North Dakota is studied using observations from two polarimetric radars and the University of North Dakota Citation Research Aircraft. The 20-21 November 2010 observations were obtained during a field project called Students Nowcasting & Observations with the DOW at UND: Education through Research(SNOwD UNDER).
POLCAST3 2010: Summer 2010 - Polarimetric Cloud Analysis and Seeding Test 3, Supporting Agency - North Dakota Atmospheric Resource Board
POLCAST3 is a cooperative effort involving the University of North Dakota (UND), National Center for Atmospheric Research (NCAR), Weather Modification Incorporated (WMI), and Ice Crystal Engineering(ICE) which is sponsored by the North Dakota Atmospheric Resource Board. The overall research objectives is to better understand the effects of hygroscopic cloud seeding at cloud base on convective clouds in North Dakota. Field measurements using the UND Polarimetric Radar, an instrument WMI Cessna 340 Aircraft, the UND Citation Research Aircraft, and surface measurements on top of Clifford Hall are between June 21 and July 23 2010.
