Lee Nozzles for Spacecraft Applications

Launching and maneuvering a spacecraft involves the precise control of volatile fluids, which is where Lee nozzles come into play. Precision nozzles from The Lee Company are small, lightweight, and easy to install – plus they’re proven to withstand cryogenic and hypergolic fluids.

The Lee Company has developed an extensive range of custom nozzle configurations to enhance the capabilities of our standard product line. Nozzles with unique envelopes are designed to meet customized dimensional and/or performance specifications. Lee HI-BAR® Safety Screens may be integrated directly on the inlet of the nozzle body to create added protection in an extremely robust, one-piece design.

Other custom designs are optimized to perform under difficult conditions typical of spaceflight operations and include custom acceptance testing, including:

  • A wide range of test fluids
  • Custom flow rates and tolerances
  • Multiple targets in a one-piece design
  • Elevated test temperatures

Spray Nozzles

Lee Spin Jet® spray nozzles utilize unique vortices and flow passages to provide a finely atomized 70° hollow cone spray pattern. The Lee Company has state-of-the-art equipment to analyze spray patterns and droplet size to determine performance across different fluids, pressures, and temperatures. Standard options are available from 6000 to 18,000 Lohms, each with a safety screen to protect against rogue particles. The nozzles are rated for operation at service temperatures up to 700°F (371°C) max and for continuous service up to 400°F (204°C) max.

Lee JELA® Lubrication Jets

Lee JELA Lubrication Jets generate a straight, well-defined stream of fluid to a predetermined target with differential pressures of 10 to 200 psid. Lee JELA Lubrication Jets are 100% tested for capture efficiency, guaranteeing that over 90% of flow will hit a predetermined target 2 inches away. These units are ideal for directing streams of lubricating oil at critical bearings or cooling oil at meshing gears, or fuel at the inside of vaporizing tubes in aircraft combustion chambers. Lubrication jets are available in four sizes from 0.125 to 0.343 of an inch with Lohm rates ranging from 200 to 7500 with a +/-15% tolerance. The 0.187-inch size is available with an integral safety screen and Lohm rate tolerance of +/-10%.

Lee Plug Jets

The Lee Plug Jet® offers an economical solution for fluid metering applications that do not require the accuracy, removability, or protective screens that are available in other, more sophisticated flow restrictors or nozzles. Lee Plug Jets are available in 416 Stainless Steel material in body diameters of 0.125, 0.187, and 0.250 of an inch, with chamfered orifices of 0.010 through 0.093 of an inch in diameter.
