At present, it seems that the "launch" of the new stealth strategic bomber is basically certain; so what specific work needs to be done before it actually takes off? In fact, the process is not complicated. First of all, although it is an strategic bomber , and it is also invisible; it still cannot escape the normal testing procedures that all aircraft need to undergo before their first flight. This is to conduct various rolling tests on the runway in advance. Only when the rolling test is proven to be completely passed, will it be possible to pull the joystick again, leave the runway and take off into the air, and then start the process of soaring into the sky. Of course, since it is a stealth intercontinental bomber, there must be some preparation steps that other aircraft, including ordinary large aircraft, do not have before their first flight. Let’s do a detailed analysis below. The first is various taxiing tests at the test airfield. The design and production unit of the new stealth strategic bomber can be determined, and the unit has its own 3,000-meter dedicated test airport. Therefore, after the new bomber completes the production and assembly of the first test aircraft,
only needs to drag out the large final assembly Factory building, you can quickly enter the main runway of the test airport to conduct various ground taxiing tests, and the final first flight process can also complete the first takeoff and landing at this site; only subsequent professional test flight tests are required. The flight transitioned to a secret aviation base. The 3,000-meter runway here is enough for large aircraft to complete all taxiing tests and first flight takeoffs and landings. For the taxiing test, low-speed taxiing is performed at the beginning; after there are no problems with low-speed taxiing, medium-high-speed taxiing is performed; and finally, high-speed taxiing before simulated takeoff is performed. At this moment, the nose wheel of the aircraft can already lift off the ground briefly, but the main landing gear has not yet finally lifted off the ground. At this time, the only thing missing from the first flight is the process of pulling the lever and pushing the throttle simultaneously. When performing high-speed taxiing almost before the first flight, the maximum speed is close to 300 kilometers per hour; because the total length of the test track is limited, when performing high-speed taxiing, it is necessary to master the timing and distance of deceleration and braking.
To leave enough remaining runway length for safe deceleration and braking, this aspect requires on-site control by a very experienced large aircraft test pilot. Although it is an intercontinental stealth strategic bomber, it still has more than 90% of the basic structural characteristics of aircraft landing gear. In other words, even if it is a large aircraft with a flying wing body or a deformed flying wing body like the B2, its landing gear system is still a traditional front triangle layout. To put it bluntly, more than 90% of the world's jet aircraft, including fighter jets, bombers, transport aircraft, and most large civilian aircraft, have an upgraded tricycle landing gear layout. Only a few special aircraft, such as the Sea Harrier , use bicycle-type front and rear main landing gear, and then add small landing gear supports at the wing tips, which is a special 4-point type. Since the landing gear of most modern aircraft is a tricycle, it must have similar control rules as a land tricycle. This means that the front wheels control the direction of operation and only bear a small overall vehicle load;
and the rear two wheels (or multi-wheel structure) bear most of the dead weight and external impact, but are basically not responsible for the adjustment of the direction, but can play a major role. The function of brakes. The low-speed taxiing of various jet aircraft before their first flight is mainly to test the maneuverability and direction sensitivity of the "tricycle" of the landing gear system. Most people think that this kind of test is completely unnecessary. Could it be that the aircraft's landing gear and three matching sets of wheels still can't run in a straight line? In the history of fighter aircraft test flights, there was a special situation when it was discovered that the landing gear system could not run in a straight line when taxiing on the ground at low speed at the beginning. For example, such a problem occurred during the first slide of fighter No. 10. Later, I went back and modified the diameter of the two wheels of the nose landing gear to solve the problem. It can be seen that the pre-flight test of any fighter aircraft, even the simplest low-speed taxiing on the ground, must be carried out in strict accordance with the requirements, and there must be no sloppiness. A real first flight from the ground will not take place until all low-speed and high-speed taxiing, including deceleration and braking systems, prove completely reliable.As the largest stealth aircraft ,
is still a question whether the stealth coating has been completely completed before its first flight. Before a certain twin-engine stealth fighter flew for the first time, the stealth coating process was not completely completed. One major advantage of doing this is that during the first flight test, the outside world will not use some secret technical means to determine the true stealth indicators of the aircraft. Because even if the basic geometric shape can already achieve 80% of the stealth indicators, the 20% of the stealth data after the final coating is completely completed is the most important. Even the B2 did not complete all the stealth coating during its first flight. This work was only completed before the later tactical test flight. If you conduct a test flight at this time, you will need to carry a Longberg lens or the like to cover up the real data. Therefore, if the new strategic stealth bomber is to prepare for its first public flight in full condition, a professional spraying workshop must be prepared in advance. If it is the first flight with a primer, this type of special factory can be built at the later test flight base. Some people say that the first flight of the strategic stealth bomber has been completed a long time ago, and now it is just a display to the outside world; this first flight is only the 1X aircraft of the second batch! This possibility cannot be ruled out.
