The excrement from the aircraft lavatory is sent to the storage box at the bottom of the aircraft by a high-pressure vortex generated by the vacuum pump, and it is treated by adding a deep blue compound with deodorizing and decomposition functions. The valve of the storage box is located outside the shell, ensuring that the excrement can only be collected by ground staff and disposed of in a vehicle after the aircraft lands, and will not be scattered in the air.

In addition, the wastewater from hand washing in the airport lavatory and the rain collected from areas such as the check-in counter is called greywater, which can be discharged through the outer shell outlet at a high altitude. Because of the high altitude, this water with no environmental pollution will dissolve under the effect of cyclones and will not cause any impact.

Expansion materials

Internal equipment of the airport engine compartment:

1. Cockpit

1. Driver observation seat:

Adjustment lever – adjust the width ratio, front and rear, left and right, and the perspective of the chair back. Seatbelt – high-strength five-point seatbelt, making the driver capable of bearing load during navigation and emergency landing.

2. Miscellaneous equipment:

Generator set oxygen, wireless communication mobile phone earphones and security equipment, etc.

2. Cabin

1. Tourist seating.

2. Restaurant kitchen, preparing Chinese fast food and drinks.

3. Lavatory, connected to the wooden floor support frame through an adjustable crank to the structure, the wooden floor is moisture-proof glass fiber, vacuum pump flushing toilet, top hole exhaust pipe.

3. Emergency equipment/equipment

1. Escape from the slide, take the slide bag stored inside the emergency and service doors, inflate and release it within 90 seconds to evacuate all staff. The gas cylinder is filled with CO2 and N2 compounds, with a standard pressure of 3000PSI, acting as a floating equipment for water emergency landing.

2. Water emergency rescue equipment.

The aircraft lavatory is also partially directly connected to the outside, and the waste from the lavatory is vertically exercising in the ionosphere, which can be instantly split and there is no need to worry about falling down.

Additionally, the great vacuum pump suction will draw the excrement into the double-layered
