If the plan of this training aircraft is not particularly eye-catching, then the next business transport aircraft plan is destined to shock the four seats. After all, the training aircraft program has only one front three-point landing gear, which is very unexpected by everyone, of course, its comprehensive performance is also very good, even those picky Romanian Air Force review committee also listened to the frequent nods, it turned out that they thought that this young man came up to look down on them, and now they feel that their understanding of the aviation industry is far less than that of this young man.

Philip turned around and hung the large picture of the business transport plane stacked in front of him, and when he turned back to face the people in the audience, he found that many people were so surprised that they even let out inaudible exclamations, all with shocked expressions on their faces, and a pair of eyes staring at the boss.

Indeed, the design of this business transport aircraft completely subverts everyone's imagination! The plane seems to be completely out of this era, it has a futuristic air to it, and every detail reveals a different flavor. The oval porthole, with a bullet-like streamlined nose, a wide cab porthole, the same front three-point landing gear, and a straight upper wing.

Philip had expected the audience's reaction, so he began to speak aloud: "What you see now is the 6-ton commercial transport aircraft scheme designed by our Dragon Soul Ordnance Complex. Let me first explain to you that at present, BFW Company, Bofors Defense Company and Dragon Soul Aircraft Manufacturing Company have reached a strategic cooperation agreement to jointly form the Dragon Soul Ordnance Industry Consortium, our Dragon Soul Ordnance Complex aims to create the most suitable weapons industry products for users all over the world, and our Dragon Soul Ordnance Complex has a unique advantage that no weapon manufacturer has, that is, the integration of resources, so that we can design and manufacture a variety of weapons, such as aviation weapons, ground weapons, light weapons, etcIn the future, we will also develop a variety of products such as surface combat weapons platforms. Okay, let's get down to business, I'll tell you more about our 6-ton business transport aircraft program. ”

For the sudden appearance of the Dragon Soul Ordnance Complex, the people present were taken aback again, after all, they had heard of the concept of this kind of alliance for the first time, although they still couldn't figure out what kind of organizational structure this union was, but they had already begun to have a deep interest in this Dragon Soul Ordnance Complex.

Philip said confidently: "According to the technical requirements of your Royal Romanian Air Force, the maximum payweight of the aircraft is 1500 kg, and the total mass of this commercial transport aircraft we designed is 6000 kg, after a series of our optimized design, the empty weight of the aircraft is 3540 kg, the minimum fuel mass is 960 kg, the maximum usable fuel mass is 1250 kg, the basic range is 1100 km, the maximum range is 1400 km, and the maximum level flight speed is 330 km/h." According to the quality and purpose of the aircraft, we designed a normal take-off wing load of 200 kg per square meter, a straight upper wing with a diagonal strut-double girder structure, a rectangular plane shape, a relative thickness of about 15%, a chord length of about 2 meters, and an integral fuel tank arranged in the middle of the wing. The vertical tail adopts a swept trapezoidal wing, and the flat tail is arranged in the middle and upper part of the tail, which is slightly lower than the main wing. The wing area is about 36 square meters, the wingspan is 18 meters, the chord length is 2 meters, the aspect ratio is 9, the fuselage height is 2.5 meters, the ground clearance is 0.5 meters, the vertical tail height is 2.5 meters, and the total height of the aircraft is 5.5 meters. The cabin length is 5 meters, the baggage compartment is 2 meters long, the cockpit is 2.5 meters long, the entrance is 1.5 meters long, the tail is 4 meters long, and the total length is 15 meters. ”

"A double-girder flat wing with diagonal struts would bring structural weight benefits, while the use of an upper wing had to do with our landing gear design. You must know that our plan is to use the front three-point landing gear, if we still use the lower wing layout, then the arrangement of the engine propeller has become a problem, the blades are too close to the ground, and even can be wiped to the ground, unless the landing gear is designed to be very high and long, but in this way the landing gear structure design has brought problems. So using an upper wing is the best layout. As a business transport aircraft, the design of the cabin is very important. The first is the cockpit, which we designed as a cockpit with a large windshield and left and right side windows, so that the pilot's vision can become very wide, and there is a driving safety and operational comfort that can take advantage of the aircraft. The design of the cabin is even more important. In order to make passengers comfortable, there must be plenty of space, for 18-seater business jets, our scheme cabin length reaches 5 meters, The height and width are 1.8 meters, 6 rows of seats can be arranged, each row of 3 seats, the aisle is 40 cm wide, and there are two luggage compartments in the front and rear of the cabin, the total volume of these two baggage compartments is not less than 3 cubic meters, in order to allow passengers to enjoy the scenery outside the cabin, we have designed 4 large area oval portholes on both sides of the cabin, and there is an emergency escape exit on the left and right sides. The non-retractable front three-point landing gear is adopted, because the speed of the aircraft is not high, so the landing gear has little impact on the flight speed, and the non-retractable landing gear can reduce the weight of the structure and improve the safety during landing. The main wheel base is designed to be 3.6 meters, the front wheels can be turned, and the size of the tires with a diameter of 450 mm and a width of 200 mm can be selected, which is convenient for take-off and landing at airstrips. ”

As soon as Philip's voice fell, many people, including the commander of the Royal Romanian Air Force, stood up, and even the four representatives of the Romanian Aviation Industry Company were surprised, this plan completely overwhelmed the Junkers' plan, let alone the Romanian Aviation Industry Company's plan. I am afraid that no aviation manufacturing company can design this plan now. Just kidding, with a maximum take-off weight of 6 tons, it can carry 18 passengers or 1,500 kilograms of cargo, and Junkers' JU52/3m is more than one size larger than the Dragon Soul Ordnance Complex's scheme!

In terms of maximum take-off weight and empty weight, the difference between the two is almost double, while the number of passengers and cargo weight that can be carried are the same; Juncker's solution has almost three times the wing area of this solution; With twice the fuel quality of the Junkers solution, the aircraft can fly 1,400 kilometers, only 100 kilometers less than the Junkers solution; Although the engine is one less than that of Junkers, it still reaches a maximum speed of 330 km/h; The most important point is that the amount of fuel consumed by the two is nearly double when loading the same number of passengers or cargo and flying the same distance, which means that the operating cost of the aircraft of the Dragon Soul Ordnance Complex is less than half that of the Junkers aircraft.

Of course, there are still many people who are skeptical about the data claimed by Philip, and they don't believe that this aircraft can really achieve the same effect after it is built! If this is the case, airlines from all over the world are afraid that they will come to grab this kind of aircraft, and how much cost can be saved by using this kind of aircraft? It's unbelievable!
