Aerospace Instruments And Payloads

Intek has a long history of participation in manned spaceflight programs that meet all of the stringent design, manufacture, performance and quality assurance requirements.  This experience and expertise translates into the company’s ability to take a total systems approach to the products and services it offers. 

Intek, Inc. was the first company to receive Boeing’s prestigious Space Station “Exceptional Company Performance Award,” at the celebration of the first year on orbit of the International Space Station (ISS).  The company was honored with this recognition for our performance during the manufacture and delivery of liquid ammonia flow meters and temperature sensors for the Active Thermal Control System for the Station.  When the award was presented to Intek’s owners at a special ceremony in Houston, Brewster Shaw, Boeing’s Vice President and General Manager, said: “Intek’s exemplary performances on critical tasks are examples of the teamwork required to make the International Space Station a success.  The recipients of this award have distinguished themselves by showing the highest level of product quality, excelling in technical and cost performance, and adhering to challenging schedules.”

Aerospace Projects

Flow and Temperature Measuring Instrumentation - Intek manufactures a line of precision flow measurement instrumentation for industrial applications. Intek has adapted this same technology to a variety of aerospace metering applications, including:

• Flow meters for the Trace Contaminant Control System of the Air Revitalization System of the Space Station.  The flow meter is a critical component of the system for purifying and recirculating air into the cabin.
  
  
• Flow meters for the Active Thermal Control System of the Space Station.  The flow meter measures the flow rate of liquid ammonia that is used to control the temperature in Space Station.   For this program, Intek also designed and built specialized test apparatus, to make the required calibration measurement using liquid ammonia under pressurized conditions and at variable high flow rates.  At the time of the project, there was no such calibration capability in the USA; this capability had to be addressed in order to meet the test and proof of performance requirements for the project.
  
  
• Temperature Sensors for the Active Thermal Control System (ATCS) of the Space Station.  Intek designed and built special “clamp-on” precision temperature sensors for the ATCS.  These sensors provided Boeing a low cost, back-up temperature measurement option.  The design maintained the integrity of the already designed fluid flow loop, since no fluid boundary had to be penetrated.
  
  
• Flow meters for the Space Shuttle MultiPurpose Logistics Module.  These meters measure the high purity Station water flow, and monitor the transfer of the water from Shuttle to Station. 
  
  
• Flow meters for the freon loop and the water loop of the thermal control system for the Space Shuttle, and the water loop of Spacehab.  Some of these meters have been in service for more than twenty years, without having been returned to the factory for performance verification or calibration.

Precision Manufacturing of Electronic Systems - Our knowledge of electronic systems and our manufacturing team with NASA certified solderers allows Intek to perform custom manufacturing and assembly of electronic systems.  One customer utilized this capability when they asked Intek to manufacture the Electrical Interface Assembly of the TCCS system, an assembly designed by Lockheed.  In the performance of this project, Intek not only executed the assembly tasks, but also examined the control system design and developed improvements to the assembly, which Lockheed accepted.

System Integration and Testing - Intek was selected to integrate the components of the Trace Contaminant Control System, and to perform certain system tests for acceptance.  The components of these assemblies were shipped to Intek for system integration and testing.  Our expertise in thermal management was a critical asset in this task.  Intek also built the cable assemblies, supported the development of the system test procedures, and participated in the complete acceptance testing of the system.

Experiment Payload Design and Manufacture

 For NASA’s Center for the Advancement of Materials and Material Processing in Space, Intek designed and manufactured two different Zeolite Crystal Growth facilities and control systems; one design which flew and operated on USML-1 and USML-2, and the other which operates on the Space Station.  These systems not only feature redundant control systems which critically control the temperature of 19 crystal growing furnaces to within "0.1EF in a 1.5ft x 2 ft cylindrical chamber, but also provide both manual and automated control.  The control system which operates the payload on Station has remote control capability, where Intek engineers can, when needed, control and operate the experiment from its communication post at our manufacturing facility.
