Researchers in the Department of Aerospace Engineering at Texas A&M University and the Texas Engineering Experiment Station’s (TEES) Texas Center for Applied Technology (TCAT) have received a third year of funding to continue work on military helicopter rotor blade erosion technology.

Blade erosion in military helicopters continues to be an area of concern, particularly in severe environments of sand and rain. The current approach to assuring safe performance relies upon frequent inspection, repair and replacement of protection films without robust and reliable procedures. The consequence is high cost. New erosion-resistant coatings are being developed but there are no physics-based models available to guide their development.

A research program is under way at Texas A&M to systematically address the erosion problem. This program, now in its third year, is focused on polyurethane films that are mounted on the leading edge of blades to provide protection from erosion caused by sand particles.

Principle investigators for the program are TCAT’s Dr. John Ayala and Dr. Ramesh Talreja, Dr. Amine Benzerga, Dr. Zoubeida Ounaies and Dr. Tamas Kalmar-Nagy with Texas A&M’s aerospace engineering department.

Dr. Tamás Kalmár-Nagy, assistant professor in the Department of Aerospace Engineering, has received the prestigious Faculty Early Career Development (CAREER) Award from the National Science Foundation (NSF).

Dr. Tamás Kalmár-Nagy

His award is the 11th CAREER award received by Texas A&M Engineering faculty in 2008-2009.

Kalmár-Nagy received the award for his proposal, “Stability and Performance of Systems with Network-Induced Delays.”

Through the next five years, Kalmár-Nagy will receive $440,000 for his research, which is aimed at developing a novel theoretical and computational framework for studying interconnected systems with random time delays.

Interconnected systems are common in chemical and nuclear plants, cars, and aircrafts, making research about their stability and security important. Since interconnected systems communicate large amounts of dynamic data, signal delays are common and, to date, can only be characterized statistically.

Kalmár-Nagy, who earned his doctoral degree from Cornell University in 2002, joined the faculty at Texas A&M University 2006. His research interests include the control of autonomous vehicles, networked control systems, systems with delay and nonlinear dynamics.

His research could impact a broad range of applications that use interconnected components, including space exploration, mobile sensor networks, teleoperated surgical robots and integrated building systems.

Kalmár-Nagy said that his project “integrates research and education at a FUNdamental level.”

Students will have the opportunity to participate in a multidisciplinary, multilevel project that emphasizes practical problem solving, creative design and the scientific method. To couple educational activities with experimental validation of the proposed theory, a distributed testbed of vehicles/robots will be built by a multidisciplinary and multilevel team under Kalmár-Nagy’s supervision.

The CAREER Award was established to support junior faculty within the context of their overall career development, combining in a single program the support of research and education of the highest quality and in the broadest sense. Through this program, the NSF emphasizes the importance on the early development of academic careers dedicated to stimulating the discovery process in which the excitement of research is enhanced by inspired teaching and enthusiastic learning.

AggieSat2, the 5-inch cube picosatellite built from scratch by the students of Texas A&M’s AggieSat Lab, is now in orbit.

The picostaellite was deployed from STS-127 Space Shuttle Endeavour’s payload bay on Thursday 30 July 2009 at 7:34:30 CDT. It communicated with the AggieSat team at the ground control station for the first time in the evening on the same day.

AggieSat2 was one of two satellites deployed from Endeavor. The other satellite, Bevo-1, has been built by students from the University of Texas.

AggieSat2 will beam information about its position (180 minutes of GPS data) by using the on-board GPS, called DRAGON, developed by Johnson Space Center. Information from the satellite will be transmitted to a ground control station set up on the Riverside campus and collected by students. The information will be sent to NASA, where it will be compared with NASA’s predictions to check the new GPS for accuracy. The mission will be considered a success after this information has been completely received by the ground control station and delivered to NASA.

AggieSat2 will pass over College Station at least once every day and remain in orbit for an estimated 4 months. On completing its mission, it will burn up harmlessly in the atmosphere.

To follow AggieSat2 on the Twitter network or Facebook, visit the AggieSat Lab website. The website is being continuously updated and has the flight teams listed on the Mission Control page along with, eventually, live health and communication window updates from AggieSat2.

The AggieSat Lab was set up in 2005 by Dr. Helen Reed, a professor in the Department of Aerospace Engineering. The lab aims to provide students with hands-on engineering experiences.

AggieSat2, a picosatellite designed and built by Texas A&M students of the AggieSat Lab, is slated for launch on the space shuttle Endeavour at 7:39 p.m. EDT on July 11.

AggieSat2, shown being weighed before being shipped off, is scheduled to travel into space on Space Shuttle Endeavour on July 11.

Endeavour will lift off from NASA’s Kennedy Space Center, Fla.

Launch countdown operations are on schedule with no issues to report, according to launch officials at the space center.

Endeavour’s launch to the International Space Station was scheduled for June 17 but had to be postponed because of a leak detected in the venting system used to carry hydrogen safely away from the launch pad.

Dr. Helen Reed, who set up Texas A&M’s AggieSat Lab in 2005, and a group of students who worked on AggieSat2 will be going to the Kennedy Space Center to watch the launch. Reed is a professor in the Department of Aerospace Engineering.

AggieSat2 is one of two satellites that will launch on Endeavour. The other satellite, Bevo-1, was built by students from the University of Texas.

AggieSat2 and Bevo-1 will be joined at launch and released from Endeavor 15 days after the shuttle visits the space station. The satellites will then separate, go into orbit, and beam information about their positions using the on-board GPS called DRAGON, which was developed by NASA’s Johnson Space Center. The GPS is being tested for accuracy.

This mission is the first of four missions planned by Johnson Space Center to demonstrate autonomous rendezvous and docking — a process in which spacecraft that are apart in space meet and join to form a single unit without human control.

The AggieSat Lab is sponsored by Johnson Space Center, Lockheed Martin, MEI Technologies, Oceaneering Space Systems, PM&AM Research, Department of Defense Space Test Program and Spreadsheet World.

The AggieSat Lab will be tracking, communicating with, commanding and collecting data from AggieSat2 through the Riverside ground station. For more information on the latest launch and updates on mission operations, visit http://aggiesat.org.

The Manureva Aerospace team's plane, the F-75 Loki

Aerospace engineering students flew the aircraft they designed and built from runway 17R at Texas A&M’s Riverside campus in May.

The flights marked the end of a two-semester design-build-test-fly aircraft challenge put forth by Dr. Leland A. Carlson, a professor in the Department of Aerospace Engineering.

During the Fall 2008 semester, Carlson asked AERO 401 and 402 students to provide a conceptual preliminary design for an Uninhabited Combat Air Vehicle (UCAV) that could carry a 2,000-pound payload for a range of 800 nautical miles at transonic speeds (Mach0.8) flying at an altitude of 40,000 feet.

The Ascension Aerospace plane, the FQ-1 Phoenix

During Spring 2009, AERO 401 and 402 faculty members Dr. Thomas Strganac, Dr. John Valasek and Dr. Jim Boyd guided three teams — Ascension Aerospace, Applied Industries and Manureva Aerospace — as they tested the models they designed and built. The models were tested in the 3 × 4 feet Low Speed Wind Tunnel at the H.R. Bright Building on campus.

The tests were performed to validate conceptual design parameters with scaled models as well as provide benchmark information for the scaled flight vehicles. Following the wind tunnel tests, the teams built and flew flying-scaled versions of their designs at the Riverside campus.

Applied Industries' plane, the XF-77 Dark Wolf

All three teams successfully completed the design-build-test-fly sequence. The Manuerva Aerospace team was awarded the Lowy Award for Spring 2009 because the selection committee agreed that Manureva’s airplane retained substantial elements of the team’s original design. For example, Manureva retained the original complexity of the wing taper, fuselage dimensions and tail configuration, and following the first flight tests, properly identified the modification necessary for the scaled version of their original design.

The following individuals are acknowledged for their assistance: John Bowling, pilot; Cecil Rhodes, mechanic/technician; and graduate research assistants Yogesh Babbar, Arun Surendran, Shalom Johnson and Drew Becket. Photos by Kasey Strganac.
