A study on a
four-tilt-rotor design, which the paper deems superior to two-tilt-rotor configuration in terms of range, speed, carrying capacity and therefore more suitable for China's needs.
A paraphrase of the conclusion is below:
The high-speed rotarycraft proposed in this paper optimizes the combination of conventional helicopter and fixed-wing aircraft and achieves fast flight speeds, strong near-ground maneuverability, and other functional characteristics. The calculation results show that its speed and range have exceeded the fastest and farthest in active service, and the near-ground maneuverability has reached or even surpassed new concepts such as . The four-tilt rotor configuration has the advantages of fast speed, long range and strong maneuverability. It has obvious advantages in carrying out transportation, delivery, emergency rescue and other tasks in the plateau and maritime environment. It can be used in conjunction with other configurations of high-speed helicopters to form China's high-speed helicopter equipment system.
Could someone help me clarify the figures in table 3? I'm confused by the term "转场航程". Also the table seems to list figures for several different scenarios (within the same mission?), with a different set of range, mission radius, flight time for each.
