Combustor Facilites – NASA

Combustion Studies Are Conducted In This Two-Test Facility Specifically in Support of the Nox-Resuction Research for the High Speed ​​Research Program and the Advanced SUBSONCED SUBSONCED SUBSONLOGY Program. CE-5B-1 is Large enough to Test Sector Arrangements of Injector Elements to Include Interactions of the Elements of the Elements and Single Larger Elements. The facility receives filtered combustion air from the 450-psig system. The air is heated in a 1,100 ° f non-vitiated heater at flows up to 20 lb/s, which can be valved to eite test stand. The airflow passes through the test section, is water spray Quenched, and is then disaged to the altitude exhaust system or the atmospheric exhaust system. The facility preheater consists of a heat exchange Fired by Four J-47 Burner Cans Using Natural Gas For A Fuel and the 40-PSIG Combusation Air. The Research Hardware Uses Astm Jet-A, JP-5, or jp-8 as a fuel.

CE-5B-1 special features

In addition to inlet and exit rakes and standard instrumentation, water-cooled gas sampling rakes are in the downstream section. Particulate measurements are taken at the exit of the combustion section. Optical Accessibility of the Combustor Section Allows Never-Before-Possible Nonintruse Nonintrous Laser-Based Diagnostics of the reacting and non-restinging flow. These include such techniques as planar laser-induced fluorescence (plif) imaging, planar mie scattering, phase/doppler particle analysis (pdpa) Grapphy. Both Rigs Share the Gas Analysis, Particulate Analysis, and Diagnostics Equipment.

CE-5B-1 System Instrumentation

CE-5B-2 is one of the two test stands in the CE-5B facility. It can be configured to Study Lean-Premixed-Prevaporized (LPP) and Lean-Direct-Injection (LDI) Concepts for Developing a Low-Nox Combust for HIGH-Speed ​​Research and Advanced SubSonic. The Non-Windowed Combusation Flame can use a 3-inch square cross section or a 3-inch-dimameter round section and has six ports available for Gas Sampling Probes. The Windowed Combustion Flame Tube takes advantage of the flat walls on a 3-inch square cross section to Install Optical Windows for non-intrusive measurements. Tests are conducted with combustion Air Inlet Pressure Ranging from 10 to 15 atmospheres with preheater and exhaust conditions described for CE-5B-1.

CE-5B-2 special features

The same laser-spoken non-infiltrous diagnostics of reacting and non-resting flowefields described for Test position CE-5B-1 Are available to this Test Section. A Typical Data Acquisition System is used for both test positions in CE-5B. In addition, most of the optical diagnostic instruments have their own data acquisition systems.

CE-5B-2 System Instrumentation

Test Cell CE-13 Combusation and Dynamics Facility (CDF) is used to Investigate Ways to Reduce Nox and Particulate Emisions from Air-Breathing Aircraft Engines. This low-spesure (1-5 ATM) Facility is used to study fuel -Ar injection schemes and how they affect fluid mixing, emissions, dynamics, and flame stability. Jet-a fuel is the primary fuel, but candidate alternate jet fuels and their effects are also studied. Standard Measurements Consist of Major Species and Dynamic Pressures. Some optical measurements available are high-speed video, Standard and Time-Resolved 2D PIV, Planar Laser Induced Fluorescence (Plif), and chemiluminescence imaging.

CE-13C Special Features

Research hardware is designed to flow vertically downwards. Preheated air is fed to the inlet air stream conditioner and then to the fuel injator. Fuel at Room Temperature is Fed Separately to the Injector. The mixed hot air and fuel mixture moves to the combustor where combustion can be observed via customized windows. The products of combustion flow through an emission sampling ring and choke nozzle/straight outlet pipe. The fuel system consists of a 25-gallon fuel tank, a pump, and a gn2 purge. A separete laser room operates various class 3B and 4 lasars (UV, Vis, Nir) to characterize fuel injection, combustor flow, and measure combustion species.
