Detailed Description

ASW19 and ASW20 Air Extraction Duct

ASW 19 and ASW20 Air Extraction Duct

General Description

ASW19 and ASW20 Air Extraction Duct is designed as a direct replacement for the fuselage inspection panel. Due to the complex nature of this design, the Air Extractor is made out of a structural rapid prototyping material that allows for an aerodynamically superior part and with hollow aerofoil sections, weighs approximately 70 grams.

Efficient extraction of the air that enters the cockpit from the vents has been considered in many glider designs over the years but only recently has it been investigated further to understand the impact on glider performance. Most gliders have openings at the base of the rear of the fin to try and allow the air to exit the fuselage efficiently. Poor extraction leads to pressurization of the cockpit causing air to escape around the canopy and through the control surfaces of poorly sealed gliders.

The Air Extractor has utilized Formula One CFD and Aerodynamics expertise and tools to create a complex shaped double aerofoil louver vent system that fits into the existing inspection panel aperture on the fuselage so no structural modifications are required. The Air Extractor has a forward fixing that doubles as a surface to ensure the air is extracted correctly.

To assist with the air flow from the cockpit vent to the Air Extractor, it is suggested that the detachable parcel shelf behind the pilot’s head is modified and additional vents are added. It is not advised to remove the parcel shelf for flight as it prevents items falling into the center section of the fuselage where the controls are located. The Air Extractor Duct is supplied with a full scale drawing which shows the location and size of holes to cut for the vents to be installed.

3. Cut out the holes from the parcel shelf. The shelf is only made of thin glass fiber and can be cut very easily. Sand the areas approximately 5mm larger than the holes on the rear face of the parcel shelf.
