1. Size comparison between Why600 & A380: Why600 is smaller than Airbus A380, but it can carry more passengers than an A380 does because of its "Y-fuselage" design.
On 13 October 2018, Malaysian newspapers have reported that the Malaysian Prime Minister, Tun Mahathir Mohamad has expressed his vision that future large passenger jets may be able to accommodate futsal court.
2. The newsreport in Malay from a Malaysian newspaper, "PM bayang kapal terbang masa depan ada futsal" ("PM imagines future passenger jets have futsal court").
Sports recreational facilities like futsal court will be useful for very long period flights that exceed 12 hours. However, futsal court will require such passenger jets to have very wide body, beyond that of the maximum practical diameter of Airbus A380.
Large aircraft engine technology has evolved significantly enabling such flights, but aircraft design, particularly that of very large passenger jets still has not. The design to accommodate very large number of passengers is done basically only by increasing the diameter and length of the fuselage, which has a practical limit.
I have produced few concepts of new fuselage design to accommodate much greater number of passengers without exceeding the practical diameter and length of the fuselage. One of these concepts is called, "Y-fuselage" (the other concepts are called "H-fuselage" & "O-fuselage").
Y-fuselage enables large passenger jets remain at the practical maximum size of A380, but can carry up twice the number of passengers, or the same number of passengers with large sports recreational facilities such as futsal courts.
Why600 is a conceptual design of large passenger jet of "Y-fuslage" that can carry 600 passengers and accommodate a recreational futsal court.
3. Why600 "Y-fuselage" Large Passenger Jet (top view).
Why600 is powered by twin powerful jet engines rated higher than the twin jet engines powering Boeing 777 for long endurance and economic flight. The position of the engines at the rear between the fuselage enables better safety and shorter turn-around time.
Being concealed between the fuselage, the engines are totally not accessible to the passengers boarding and leaving Why600, unlike the current situation where wing-mounted engines of conventional large passenger jets are exposed to the boarding and leaving passengers.
With the engines concealed, they can be safely ignited and running while the passengers are boarding, and therefore allowing early engine warm-up. This enables shorter turn-around time for Why600.
The positioning of the twin engines at the rear and between the fuselage frees the wing from having any engine attached to it. Therefore, the wing is lighter and more aerodynamic. A lighter wing means less complicated and lower cost production. Such aerodynamic "clean-wing" also translate into higher efficiency and lower operational cost. This is a major improvement in the design of large passenger jets as almost all of them have wing-mounted engines.

The futsal court however is not a full-size one, but large enough for recreational futsal and to be utilized as gymnasium. During flight, there can be some gymnasium exercise programs with instructors offered to the passengers.

6. Front view of Why600.
A special utilization of Why600 will be an effective platform for microgravity experiment, where large aircrafts are flown in "multiple parabolic jump" to simulate microgravity environment to their passengers and payloads. Each parabolic jump produces up to 20s microgravity time, and a series of 15 parabolic jumps will produce 300s of total microgravity time considered significant enough for effective microgravity experimentation and activities.
7. A flight profile simulation of an A310 microgravity aircraft.
A friend of mine, Oliver Ullrich who is a leading microgravity flight scientist that has flown many hours of microgravity experimentation, has said the the fuselage width of a microgravity aircraft is more significant than the length of its fuselage. Why600 with its fuselage width more than twice that of A380 will be a very effective platform for microgravity experimentation and activities.
8. The fuselage width of a microgravity aircraft is significant for microgravity experimentation and activities. For such, Why600 will be a very effective microgravity laboratory.
Y-fuselage design results in twin fuselages at the rear with a significant area between them. If the area is utilized as part of the rear cabin, the aircraft can carry many more passengers, resulting in Why1000 (see Why1000).
Building a very large passenger jet bigger than A380 may not be practical not only for its design and production complication, but also for airport standardization, although there is such requirement to carry very large number of passengers. "Y-fuselage" maybe is the most practical approach to design such passenger jet that can carry very large number of passengers, but limited by the practicality of size. It is also maybe a break-through in the clean-wing design of large passenger jets.
