SE-11 Facility Description
The SE-11 Particulate Aerosol Laboratory is used to study jet contrails at upper atmospheric conditions utilizing various particulate and chemical analyzers. A nitrogen system supplies an altitude chamber with cold gaseous nitrogen at temperatures corresponding to altitudes ranging from 5,000 ft. to 30,000 ft. A burner provides exhaust emissions to a small nozzle mounted in the altitude chamber. The chamber nozzle simulates a scaled model of a jet engine exhaust nozzle. Sample emissions can be acquired before the altitude chamber and at various heights inside the chamber. Nitrogen and emissions exit the chamber and are warmed by a heat exchanger and vented to the Engine Research Building (ERB) altitude exhaust.

SE-11 Special Features
For analyzing purposes the facility uses an exhaust gas analysis bench, a Fourier transformed infrared spectrometer, a gas-chromatograph-mass spectrometer, a particulate analyzer, a thermogravimetric analyzer, and a simple chromatograph.
