About this plane, first I just wanted to modify it in order to have a wider range. But after that, I became interested in further modifications. The original plane has tons of engines, as the original builder said: too many engines. This plane has a really poor range when its infinite fuel tank is removed. I removed the engines, made a large wing, and installed a rotator connected to the engine (similar to thrust vectoring, but the difference is the rotator lets all the engines move up and down, not only the nozzle,because i dont knok how to write a Flying Control), giving it higher maneuverability and range. The first plane I modified could only fly up to 16 km at sea level.
When it came to version 3.9, it could fly up to 54 km, but it still had poor maneuverability when landing. It must have an engine installed on the vertical stabilizer to provide upward thrust, with the help of engines, it still needed a high speed to land. So I continued to improve it.
At version 4.3, I changed the many turbojet engines in front of the plane to 4 BFE150 engines. Its range increased significantly, and the landing problem was solved. It also had really high maneuverability; it could even perform a post-stall maneuver when supersonic and at a high altitude. But it was hard to turn at that altitude due to reduced weight, and I found it had the capacity for vertical takeoff (but can't land vertically). I started to work on it, but my limited FT knowledge couldn't make this dream come true.
After version 4.3, I focused on range because I found it had poor fuel efficiency at low altitude, even though I installed 13 engines. It could fly up to 100,000 ft, but when reaching that altitude, it would use nearly half of all fuel. I used many methods to increase fuel efficiency, such as installing a helicopter engine on the plane and trying to use it to climb to a target altitude(at a high altitude,in this condition jet engines will have a better fuel effiency), then switching to jet engines. But the helicopter engine couldn't provide enough thrust; it didn't extend the range much and was easy to lose control. So I concentrated on the 13 engines installed on the plane.
After that, I still updated some small parts, such as updating the landing gear at version 4.5.
When it came to version 4.8, I changed some J50 engines to J90 and removed some engines. Before, it could fly up to 1000 nmi at 100,000 ft; after that, it could fly up to 4500 km at 100,000 ft (version 4.93).
And after many months, I had read some knowledge about delta wings and some aerospace knowledge, and I found a new concept - the dual delta wing, and I quickly used it for my plane. But the performance like max speed, wing loading, maneuver, and landing performance was worse than the original delta wing. But I am not satisfied with its speed and fuel consumption at low altitude, but I don't know how to edit it, so I just deleted some engines and part of the wing area (4.9d), and I found its performance has improved significantly, like max speed reaching 1500 kts, max altitude reaching 103,000 ft. But its wingtip stall really affects high angle of attack flight. When I tested its low-speed performance, sometimes it occurred at 170 kts. And I had found ways to solve it, but it seems like some of them can't solve the issue, like adding wing blades or winglets... but this seems like it can't work under SimplePlanes's physics. And I am experimenting on how to solve it.
After version 4.9d (truly is 4.95d), it seems like this plane is hard to update.
This plane still isn't perfect. Although I joined 4 years ago, my aircraft building skills are like those of someone who joined a month ago. I can't even make a print because I think my custom paint is really ugly. So, I have used the default print... sorry.
