Kansas University Meridian Monitors Ice Flow

Kansas University’s school of Aerospace Engineering (KUAE) has used MTM®45-1 prepreg from Advanced Composites Group (ACG) to build a fleet of Meridian UAS designed to monitor the flow of ice sheets in Greenland and Antarctica.
KUAE selected ACGs MTM45-1 for the Meridians wings, empennage and fuselage structure because its combination of properties makes it ideal for the out-of-autoclave (OoA) production of aircraft primary structures. Indeed, MTM45-1 has a flexible curing temperature, high performance and toughened epoxy matrix system optimised for low pressure vacuum bag processing.
MTM45-1 may be cured at temperatures as low as 80°C (176°F), allowing the use of low cost tooling for prototypes and short production runs. OoA process cost savings for aircraft manufacturers can equally be applied to other less critical structures such as fairings, which are normally produced via autoclave curing. MTM45-1 can also be autoclave cured, meaning that it can be used for more critical structures.
A flame-retarded variant of MTM45-1 (MTM45-1FR) is also available and has been shown to meet the requirements of FAR 25.853.
Under a 5-year, $19 million research grant from the National Science Foundation to Kansas University’s Center for Remote Sensing of Ice Sheets (CReSIS), KUAE's mission was to provide an aerial platform for ultra-sensitive ice-penetrating radar developed in Kansas University’s Electrical Engineering and Computer Science department. Information on the morphology of the ice, especially the condition of the ice where it meets bedrock, is being derived from radar data, which is improving glaciologists predictions of the flow of ice sheets into the oceans.

The Meridian UAS, developed by a team of current and former students under the guidance of faculty members, including Rick Hale, Shah Keshmiri, Mark Ewing, Dave Downing, Ray Taghavi and Richard Colgren, will operate in Greenland between July and August 2011 and then in Antarctica between December 2011 and January 2012.
