We also support commercial space programs and provide systems engineering services to the oil and gas industry. Our primary locations are at NASA’s Johnson Space Center (JSC) in Houston, TX and the Marshall Space Flight Center (MSFC) in Huntsville, AL. Barrios employees have the opportunity to contribute to the US Space Program through work on the International Space Station (ISS), Orion, Space Launch System and Exploration programs. Barrios Technology is the prime contractor for the Human Space Flight Technical Integration (HSFTIC) contract, Consolidated Program Support Services (CPSS) Project Coordination (PC) and Research, Engineering, Mission Integration Services (REMIS) contracts along with subcontractor support to multiple prime contractors as listed below.

We provide a full spectrum of engineering, operations and related technology services in support of the aerospace community and have successfully supported NASA for 40 years. is a woman-owned and operated small business headquartered in Houston, Texas.
Operations capability development support is required as NASA defines requirements associated with the emerging options for the exploration initiatives and potential new programs, including - but not limited to - the Orion Multi-Purpose Crew Vehicle Program, the Space Launch Systems Program, the Lunar Precursor Robotics Program, the Human Research Program, the Exploration Technology Program, the Commercial Crew Program, commercial cargo, and advanced technology and research.īarrios Technology Ltd. This includes support to mission preparation, crew, flight controller, instructor, and analyst training, as well as real-time mission execution activities related to exploration operations and space station operations.

The Integrated Mission Operations Contract II (IMOC II) provides support and products for spaceflight operations capability development and execution for the Mission Operations Directorate, the International Space Station Program - including the Avionics and Software Office, and the Flight Crew Operations Directorate at NASA's Johnson Space Center in Houston. Equivalence ratio control was successfully achieved under all of these conditions, showing that a suitable processing of multiwavelength data allows premixed gas turbine combustion control.Our long-term client relationship with KBR has led to a need for an Extravehicular Activities (EVA) Operations Flight Controller on the Integrated Mission Operations Contract II (IMOC II) contract at Johnson Space Center (Houston, TX).
The performance of the sensor and control system is assessed by simulating changes in fuel quality and by operating the system with contaminated windows. Closed-loop control using this chemiluminescence sensor has been tested over a broad range of, operating conditions.
These data are collected in a lookup table, which is then used to monitor the equivalence ratio and control the fuel mass flow rate. Radical emission data in the form of intensity ratios OH */CH * and CO 2 */CH * are first measured during an, off-line combustor identification step carried out with the same monochromator. Spectral distributions, are analyzed in real time to determine the equivalence ratio according to a novel method described in this paper. The sensor comprises a broadband, low-resolution grating spectrometer scanning the light emitted by the burner in the range 250–850 nm. A control system based on a multiwavelength chemiluminescence sensor has been developed and tested to adjust the operating point of an optically accessible, lean premixed methane/air burner operated under pressures up to 20 bar and equivalence ratios ranging from 0.5 to 1.2, as typically found in premixed gas turbine combustors.
