鸣镝-22高超声速宽域飞行器验证机
MD-22 Hypersonic Wide-domain Flight Test Vehicle

Author's Notes 作者的话：

大家好！这是我第一次尝试在《简单飞机》里还原现实中的飞行器——中国的鸣镝-22高超声速宽域飞行器验证机。我是一名有高功能ASD的高一学生，制作水平还很有欠缺（像小学生一样），这个作品只使用了94个零件，因此可以在安装了Smoke Trails的手机上轻松运行。欢迎大家指点和建议！
​Hello everyone! This is my first attempt to recreate a real-life aircraft in SimplePlanes—China’s MD-22 hypersonic wide-domain flight test vehicle. As a high school first grade student with high-functioning ASD my design skills are still developing like an elementary school age. This model uses only 94 parts, making it easy to run on mobile devices with the Smoke Trails mod installed. I welcome your feedback and suggestions!

About the Name 关于名字

飞行器的名字“鸣镝”出自毛泽东主席《满江红·和郭沫若同志》中的“正西风落叶下长安，飞鸣镝” ，寓意响箭离弦，锐不可当。虽然美国麦道公司的缩写也是MD，但这个作品中的“MD-22”代表的是MingDi-22 / Whistling Arrow-22，而非Mcdonnel Douglas-22。
The name "鸣镝"(MingDi) comes from Mao Zedong’s poem "Man Jiang Hong: Reply to Comrade Guo Moruo":
"正西风落叶下长安，飞鸣镝。"("As the west wind sweeps the fallen leaves down Chang'an, The whistling arrow is shot.")
It symbolizes an arrow whistling through the air—swift and unstoppable. Although the abbreviation "MD" overlaps with an American aircraft brand, here "MD-22" stands for MingDi-22 / Whistling Arrow-22, not McDonnell Douglas-22.

Aircraft Overview 飞行器介绍

MD-22是中国科学院力学研究所等单位研发的一款临近空间宽域飞行器技术验证机 ，飞机使用V型垂尾和可能搭载的旋转爆震或超燃冲压发动机，设计上能以7马赫的高超音速在临近空间飞行，航程可达8000公里 ，并具备可重复使用能力 ，其在宽域飞行和组合动力方面的探索为未来空天技术发展积累了宝贵经验。2025年2月，鸣镝22在临近空间（20-100公里高度）完成关键飞行试验，最高速度达7马赫（约8570公里/小时），试飞中验证了宽域飞行能力。‌‌
The MD-22 is a near-space wide-domain flight test vehicle developed by the Institute of Mechanics, Chinese Academy of Sciences, among other institutions. It features V-tail stabilizers and may be equipped with rotating detonation or scramjet engines. Designed to fly at hypersonic speeds of up to Mach 7 in near-space, it has a range of approximately 8,000 km and is reusable. Its research into wide-domain flight and combined propulsion systems provides valuable experience for future aerospace technology.
In February 2025, the Mingdi-22 completed a key test flight in near-space (20–100 km altitude), reaching a maximum speed of Mach 7 (about 8,570 km/h) and validating its wide-flight capabilities.

Real Aircraft Specifications 真实飞机参数：

鸣镝-22机长10.8米，翼展4.5米，重量1吨，最大载荷600公斤，航程8000公里，可实现跨洲际打击。‌‌据网络推测，该飞机验证了空天往返能力，被视为第六代乃至第七代战斗机的验证平台。
Length: 10.8 m
Wingspan: 4.5 m
Weight: 1 ton
Maximum Payload: 600 kg
Range: 8,000 km
Capable of intercontinental strikes

In-Game Model Specifications 本作品参数：

机长12.8米，翼展5.9米，重量6.76吨（由于没有合适的参照物，游戏中导入的图纸可能比真实飞机稍大，造成了这一结果）
Length: 12.8 m
Wingspan: 5.9 m
Weight: 6.76 tons
(likely due to imported Blueprints without reference scaling)

​​Performance Notes 飞机性能：
当你在空中释放后，飞机会依靠喷气发动机自动爬升，我实测在Wright Final Approach出生点生成时，最高曾到达11357米左右的高度，之后会缓慢下降。
飞行中飞机会不自觉地向右侧滚转，需要你持续手动微调方向来保持平衡。另外，大幅度俯仰操作也容易让飞机失控。
为了尽可能维持高度，我在机身前端一个隐藏位置安装了一台斜向上的辅助喷气发动机。
When released mid-air, the aircraft climbs automatically using its jet engine. From the Wright Final Approach spawn point, it can reach a maximum altitude of about 11,357 m before gradually descending.
The model tends to roll slightly to the right, requiring manual adjustments to maintain balance. Sharp pitch changes may cause instability.
To sustain altitude, an auxiliary upward-thrusting jet engine is hidden in the nose.

Known Issues 存在的问题：

这架飞机虽然拥有起落架，但无法从地面正常起飞，需要在空中出生点生成，或使用轰-6之类的母机作为搭载平台，在高空释放。
正如刚才所说，飞机容易出现滚转和失控问题，且由于游戏空气阻力限制，飞机的最高速度只能达到2600公里/小时左右。
为模拟火箭发动机的烟雾，该飞机使用了Smoke Trails 2模组来生成烟雾轨迹。
Despite having landing gear, the aircraft cannot take off from the ground. It must be spawned mid-air or released at high altitude from a carrier aircraft (such as an H-6 bomber).
The model is prone to rolling and instability. Due to in-game drag limits, its top speed is capped at about 2,600 km/h.
The Smoke Trails 2 mod is used to simulate rocket exhaust effects.

​​Final Words 最后的话

非常欢迎大家尝试将此作品与其他空中发射平台结合，这是对我作品的最大支持！
I encourage you to try integrating this model with other aerial launch platforms—your experiments are the greatest support for my work!
