Chapter 2307: Chapter 2267: Accelerated Generally speaking. This belongs to manufacturer testing. Therefore. If it is officially put into use in the future, it still needs to be taken care of. The operation manual will definitely not recommend: Park anywhere freely, if it breaks, it’s my loss. What a joke! In fact. Wind. Rain. Snow. Thunder. ... Various environments, it can handle them all. However. The manual will definitely state: 1. It is not recommended to take off without preheating after staying for more than an hour in a zero-degree environment. 2. It is not recommended to park outdoors for an extended period. 3. It is not recommended to take off in dusty weather. ... Dozens of cautionary notes, stretching across hundreds of pages, cannot be vague. Just like all military equipment, from the design stage, it can be operated in various harsh environments. But. No one dares to write in the operation manual: This thing is tough, do as you please! ... The next day. Morning. The warm sunlight pours down, but unfortunately, standing under the sun, it is still quite cold. When the snow melts around, it absorbs a lot of heat, feeling chilly. Cafeteria. After enjoying a delicious breakfast, everyone returned to their posts. Today, they are to start a full project rehearsal. They were pretty tense, fearing any mishaps. Ten o’clock. Tower. Top floor. This place is decorated quite sci-fi, with three curved control consoles, and dozens of people sitting next to computers, busy at work. The computer screen is glass. Hmm! Just like in the movies, transparent, touch-screen, but primarily using the mouse to prevent misoperation. Looking cool shouldn’t go too far. Some features are indeed good. But. One must also consider the real situation and the issue of interfacing with external data as many professional software only supports the mouse. Any change will take time. ... They have many tasks. Dispatch. Command. Contact. This flight, although only at mid and low altitudes, and in a sparsely populated area, still requires flight clearance from airspace management. Among them. Only within a three-hundred-meter range over the base does not require an application. Complicated. But as long as flying is possible, it’s fine. "Report, pre-launch flight clearance has been obtained!" the liaison officer reported. This is not a civilian-controlled area, so permission from the air force is needed. Generally not refused. Unless. There is a task or special circumstances in that area, but this place is very secluded. Even with fighter jet patrols, there won’t be any conflict with helicopters. The altitudes are different. Thus. It has never been refused before. "Good." "Start the first item." "Yes." With a command. Instantly. Six helicopters powered up, rising straight into the sky, then, the four large propellers began to tilt, propelling the aircraft forward. ... "Speed fifty, normal." "..." "Speed eighty, normal." "..." "Speed one hundred, normal." "..." Information kept coming in, and soon it broke through two hundred kilometers per hour. Being unladen, this speed hasn’t reached the limit of this aircraft. It’s still increasing. "Speed two hundred and thirty, normal." "..." "Speed two hundred and seventy, normal." "..." "Speed three hundred, normal." "..." Finally. Stabilized at the cruising speed of three hundred and sixty kilometers. At this point, they disappeared from the tower’s view; as planned, they need to fly 120 kilometers at an altitude of three hundred meters. Then. Climb. One thousand meters. Two thousand meters. Four thousand meters. Six thousand meters. A total of four altitudes, each flown for twenty minutes. Previously, only one altitude was tested each time. This time, it was about connecting the project for testing. Six thousand meters. Below commercial airline altitude, considered the design limit. It’s not that it can’t fly higher, but it’s unnecessary. The primary purpose of this thing is not aviation. No need to fly up shoulder to shoulder with airliners. ... "Speed three hundred and sixty, flight stable, status normal!" "..." "Speed three hundred and sixty, flight stable, status normal!" "..." Report every minute. At this time. In front of the huge glass screen, Tang Qing stood with hands behind his back, standing quietly. On it was the running position of six aircraft, using GPS navigation. Can’t do. Want to use Beidou. Still have to wait a few years. The Beidou series satellites began launching in 2000 but didn’t launch the first Beidou navigation satellite until 2007. Subsequently. After two years. This year in April, only the second Beidou navigation satellite was launched, and to achieve precise positioning of a point, at least three satellites are required. Longitude. Latitude. Height. Generally, there will be an extra one for correction and backup. Therefore. For Beidou to truly have high-precision positioning functions, it will have to wait until the latter half of next year. After launching another two, a basic positioning array can be formed. ... On the screen. Only the map location can be seen, but not the commodity. However. Tang Qing could see, in the sky, their own satellite, transmitting real-time images, extremely clear, and even capable of high-speed tracking. Capable of seeing the drivers, quite impressive. Simultaneously. Countless data flashed past the corner of his eye, displaying the equipment’s operational status. Normal. Normal. Normal. Not a single alert. "One thousand meters fixed cruise completed, cruising speed three hundred and sixty, throughout normal, no equipment alerts." "..." "Three thousand meters fixed cruise completed, cruising speed three hundred and sixty, throughout normal, no equipment alerts." "..." An hour and twenty minutes later, the aircraft hovered over the base, not descending, because they still need to retrace the route just flown. However. This time, they need to add some speed. "Begin the second item, proceed at full power with an empty load." "Yes." Receiving the command, the aircraft took to the skies again, swiftly ascending to the cruise speed powered by the propellers, then, in the middle of the cantilever. "Buzz! The vertical turbo engine began to rotate, turning horizontal. "Buzz! "..." The noise grew larger, almost roaring in the end, an unavoidable consequence, the sound of air friction from the turboshaft+turbine is significant. "Secondary power, output ten percent." "..." "Secondary power, output thirty percent." "..." Seen. In the sky, the speed of the six aircraft increased again. Raced out, during the design, Tang Qing incorporated dual power, one relying on the propellers and the other on the turbine in the middle of the cantilever. Of course. Technologically, it wasn’t as challenging as Boeing’s aviation engines, as the aircraft is hybrid, hence, the performance requirements for aerospace engines are much lower. Powerful. Lightweight. That’s sufficient. A bit rough is fine, stable output, meeting the requirements suffices, under extreme simplification, engine components reduced by two-thirds. In short. Usable is fine, durable is fine. ... A thousand miles away. At an air force base. Tower. Airspace management center. "The speed is quite fast, three hundred and sixty, which is considered top-notch in the helicopter field, but it’s odd, why apply for a speed of five hundred kilometers?" "Who knows." Actually, they don’t have a heavy workload daily, and the sudden appearance of a civilian test flight piqued their curiosity, watching the moving dots on the screen, discussing eagerly. In this case. Mostly just for the novelty. After all. How to say it was still designed by Tang Qing, military use? Might as well forget it, so large, too conspicuous, definitely a target, not even suitable for transporting materials. Suddenly. The screen flashed. "It’s speeding up!" Someone exclaimed.
