A Technical Talk on "Application of Sensors in Missile and Launch Vehicles: Future Trends"
This is the Inaugural Event of IEEE Sensors Council Chapter, Methodist College of Engineering and Technology Student Branch. This event was planned to inaugurate the newly formed Sensors Council Chapter in the Student Branch followed by a talk on Application of Sensors in Missile and Launch Vehicles: Future Trends by Dr. Joydeb Chattopadhyay.
Abstract of the talk:
Sensor converts physical event to the information that is processed and analyzed by the computing system for a specific purpose. Sensors are used in all application like agriculture, medical, transportation, aerospace technologies and many others. In this talk role of sensors will be discussed in the area of Missile and Launch Vehicle. These two systems have many similarities in operation. Missiles are required to hit the target located at long distance and Launch vehicles are required to launch a satellite to the particular orbit. They both have multiple stages and follow a similar trajectory in the boost phase. They use large number of sensors in different form. These sensors can be broadly categorized in two roles like a) Guidance, control and navigation b) Telemetry operation.
The vehicle is provided initial coordinates of the launch point and also the destination point. The computer embedded in these vehicles receives sensor data and execute Navigation and guidance algorithm and control the flight path through set of actuation system. Gyros and accelerometers are the basic sensors used for this purpose. In addition, there are other sensors like current sensors and LVDTs used for actuation sensors. To achieve best hit seekers are used in different frequency band. Flight vehicle has many subsystems like structure, propulsion, aerodynamics, avionics, power sources. These system performances are assessed by the measurement of difference parameters like temperature, pressure, strain, acoustic, vibration, current, voltage etc. They are captured through the sensors suitably attached to the particular system. These are acquired and by data acquisition system and transferred to telemetry system with pulse code modulator and transmitter. The transmitted signal is received at the ground station for necessary analysis and decision making. These sensors are discussed in details and also shortcomings of the sensor interfacing the data acquisition system and to the telemetry is brought out. A CAN bus-based architecture with intelligent sensors is brought out as future work.
