Application Requirements: Ground-based simulated ignition tests of rocket engines are crucial, requiring them at various stages including rocket system design finalization, prototype testing, and batch inspection. The main solid rocket engine test parameters of concern to designers at each stage include: engine thrust, combustion chamber pressure, engine surface and space temperature, engine surface and nozzle strain, displacement, ignition delay time, vibration, noise, ignition sequence, dynamic pressure, and ignition zero moment. Technical Challenges: The system presents a complex array of parameter types, including steady-state analog parameters, steady-state digital parameters, and dynamic parameters such as vibration. Due to the high cost of solid rocket engine testing, the reliability requirements for the acquisition system are extremely high. Solution: Given the large number and variety of parameters to be acquired and the stringent reliability requirements, a VXI bus architecture was adopted for the entire system. Considering the system's use on a fixed test bench, the VXI Technology CT-400 rack-mount 13-slot VXI chassis was selected, along with an embedded zero-slot controller to enhance overall system performance. Steady-state simulation parameter conditioning and acquisition are achieved using VT1413C 100kHz scanning A/D modules and corresponding SCP signal conditioning. Specifically, this involves three VT1413C modules, sixteen VT1503A 8-channel programmable filter and amplifier SCP modules, four VT1502A 8-channel 7Hz low-pass filter modules, and four VT1506A 8-channel 120Ω strain conditioning modules. Steady-state digital signal acquisition is achieved using one VT1419A multi-functional measurement and control module and four VT1536A isolated digital input modules. Vibration, noise, and dynamic pressure acquisition are achieved using two VT1432A 16-channel 51.2kHz parallel A/D modules. Due to the large data volume of the entire system, a VT2216A module was selected as a high-speed data stream disk, which contains two SCSI hard drives, each with a storage capacity of up to 73GB and a data throughput of up to 15MB/s per SCSI drive. In addition, this module has two SCSI interfaces, allowing for the connection of high-speed SCSI hard drives or other SCSI devices. Operating mode: During system operation, three VT1413C drives and one VT1419A drive work synchronously, transmitting the acquired signals simultaneously to the embedded zero-slot controller and the VT2216A data pass-through disk via the VXI backplane bus. Two VT1432A drives transmit the acquired data to the VT2216A data pass-through disk via the local bus, and simultaneously transmit some data to the embedded zero-slot controller via the backplane bus. The VT2216A simultaneously receives steady-state and dynamic acquisition data and continuously records them to form a test data file. Users can monitor the test parameters in real time via a display. After the test is completed, users can access the test data and perform various analyses using data post-processing software. Editor: He Shiping
