DALBIT-1, a miniature-sized, fully integrated, Earth-based lander test bed was designed and developed for the vertical takeoff and vertical landing flight demonstration. Mission and design requirements and vehicle subsystems were selected to accommodate the vertical takeoff and vertical landing preliminary flight demonstration. Subsystems, including the propulsion system, structure, avionics, and ground control station, were designed, developed, and integrated as a system. The flight control system of DALBIT-1 was generated to enable the vehicle an autonomous flight and was validated using a computer simulation in a MATLAB/Simulink environment. Simulation results show that DALBIT-1 adequately follows the predetermined trajectory and softly lands on the surface. The developed test bed performed a series of static fire tests and water/propellant flow tests to enhance the predictability of the flight control system. Using the developed flight control system, finally, the preliminary flight demonstration was conducted and proved the capability of the test bed of performing a vertical liftoff, vertical landing flight.

DALBIT-1 是一种微型、完全集成的地球着陆器试验台，是为垂直起飞和垂直着陆飞行演示而设计和开发的。选择了任务和设计要求以及车辆子系统以适应垂直起飞和垂直着陆的初步飞行演示。子系统，包括推进系统、结构、航空电子设备和地面控制站，被设计、开发和集成为一个系统。DALBIT-1 的飞行控制系统是为了使车辆能够自主飞行而生成的，并在 MATLAB/Simulink 环境中使用计算机仿真进行了验证。仿真结果表明，DALBIT-1 充分遵循预定轨迹并轻柔地降落在表​​面上。开发的试验台进行了一系列静态火灾试验和水/推进剂流量试验，以提高飞行控制系统的可预测性。最后利用研制的飞控系统进行了初步飞行演示，验证了该试验台的垂直升空、垂直着陆飞行能力。
