Features

Uses the FAA-approved NexGen aviation fuel burner, developed to replace discontinued legacy burners (Park DPL 3400. Lennox OB-32. Carlin 200 CRD).

Retains the operating principles of previous burner generations while allowing more precise measurement of fuel and air test parameters.

Modular design supports future FAA upgrades without replacing the entire system.

The burner cone is fabricated from corrosion-resistant and high-temperature alloy for durability in severe thermal conditions.

The NexGen burner includes baffle, fuel nozzle, igniter, fuel rail, mounting plates, ventilation duct, housing, muffler, and acoustic resistance components.

Equipped with fuel pressure gauge, fuel solenoid valve, fuel temperature sensor, air pressure regulator, and air temperature sensor for stable control.

A temperature-controlled ice bath system (≥ 2 × 0.14 m³) allows regulation of fuel temperature before combustion.

Flame characteristics can be adjusted by changing the fuel nozzle and air pressure to meet different standard requirements.

The burner is covered with a thermal insulation blanket to protect fuel lines and the burner body.

Capable of delivering flame temperature of at least 2000 ± 50 ℉ and heat flux of at least 10.6 W/cm².

Mounted on a powder-coated steel frame with integrated digital scale for accurate positioning and measurement.

Includes a calibrated load cell weighing system.

Features a movable seat cushion test fixture and a movable drip collection tray.

Calibration uses a thermocouple comb composed of seven grounded K-type thermocouples (1.6 mm diameter, ceramic-insulated, metal-sheathed, 30 AWG wire), fixed on an angle bracket for standardized placement on the specimen frame.

Includes a radiant heat flux sensor with cooling system, installed on a fixed support bracket.

Accessories

The system is supplied with the following components:

NexGen aviation fuel burner

Seat cushion test frame

Dynamic motion system

Fuel temperature control ice bath

Thermocouple calibration comb

Radiant heat flux sensor with cooling unit

Powder-coated steel support frame with digital scale

Movable seat cushion test fixture

Movable drip collection tray

Burner thermal insulation blanket

Test Procedures

Mount the aircraft seat cushion specimen on the designated test frame.

Connect aviation kerosene supply and compressed air (≥120 PSI).

Set and stabilize fuel temperature using the ice bath system.

Adjust air pressure and fuel parameters according to the selected standard.

Ignite the NexGen burner and allow the flame to stabilize.

Position the flame relative to the specimen and begin exposure.

Monitor flame temperature and heat flux using thermocouples and sensors.

Observe flame spread, burning behavior, and dripping characteristics.

Record test data and evaluate results according to the applicable standard.

Maintenance Information

To ensure reliable and consistent operation:

Clean the fuel nozzle regularly to prevent blockage.

Inspect fuel lines and valves for leakage before each test.

Calibrate thermocouples and heat flux sensors periodically.

Replace the burner insulation blanket if damaged or degraded.

Maintain proper ventilation in the test area.

Keep the compressed air system dry and free from oil contamination.

Verify load cell calibration before formal certification tests.
