该项目详细介绍了低成本、3D打印火箭发射器和制导火箭系统的开发，主要使用消费级电子产品构建。该火箭采用折叠式尾翼和前翼稳定，由ESP32飞行计算机和MPU6050 IMU控制飞行。发射器集成了GPS、指南针和气压传感器，用于精确的定位和遥测。该系统使用Fusion 360进行设计，OpenRocket进行模拟，并对机械、电子和发射性能进行了广泛的迭代测试。所有核心工程组件——包括CAD文件、固件源代码和模拟数据——均公开可用。值得注意的是，整个原型机的成本约为96美元，证明了使用易于获取且价格实惠的材料构建功能性制导火箭系统的可行性。更多开发媒体和文档可在链接的Google Drive文件夹中找到。

一款96美元的3D打印火箭，其细节在GitHub上公开，因其能够使用5美元的传感器在空中重新计算轨迹而备受关注。该项目引发了争论，一些人赞扬了创造者的工程技能以及先进技术民主化的潜力，这些技术此前仅限于政府。然而，许多评论员表达了担忧。该项目的宣言暗示了潜在的不对称战争用途，并且创造者公开讨论实施便携式防空导弹系统（MANPADS），引发了ITAR违规等法律问题。伴随该项目的视频包含无人机战争的画面，并且有争议地出现了大卫·科雷什的形象。用户推测创造者可能正在寻求国防合同，并质疑考虑到其潜在的危险应用，该项目在GitHub上公开可用的时间会持续多久。这场讨论凸显了开源国防技术更广泛的趋势，包括雷达设计方面的最新进展。

This project is a proof-of-concept prototype of a low-cost rocket launcher and guided rocket system built using consumer electronics and 3D-printed components. The rocket uses folding fins and canard stabilization controlled by an onboard ESP32 flight computer and MPU6050 inertial measurement unit, while the launcher integrates sensors such as GPS, compass, and barometric modules for orientation and telemetry. The system was designed in Fusion 360, simulated using OpenRocket, and developed through iterative mechanical, electronics, and launch testing. The total hardware cost of the prototype is approximately $96.

This repository contains the core engineering components of the project:

mechanical CAD files for the rocket and launcher
firmware source code for the rocket flight controller and launcher system
OpenRocket simulation files used for aerodynamic stability analysis
