Senior Project Sponsors 2007-2008 School of Electrical Engineering & Computer Science Oregon State University Project Description This design project will give you an opportunity to work with some advanced avionics equipment designing a stabilization system for a Bell 214 helicopter. The current stabilization system is made of three components: the Stabilization Control Automation System (SCAS), the Attitude/Altitude Retention System (AARS) and the Fly By Wire (FBW). We will be working on the SCAS system, due to its relative simplicity. The SCAS system is driven by several actuators that dampen the pilots input from the flight controls, making the helicopter less sensitive and less likely to crash. These actuators fail often and are very pricey to replace, making the current system very expensive. The purpose of this project is to provide a more reliable, cost effective solution to the current model. We will be working closely with Helicopter Transport Services (HTS) based out of the Corvallis Airport as they will be providing the aircraft for us to analyze, test and work on. HTS also has a hanger and workshop that we will have limited access to providing other resources and tools to aid in the successful completion of this project. This is an exciting opportunity to work with some state of the art optical gyroscope systems while learning about the vast and interesting world of avionics. Key Features • Dampens pilot inputs connecting the flight controls to the rest of the helicopter • Uses Allen Bradley PLC computer to monitor the system • Uses Crossbow optical gyroscope to measure both the current position and the rate of change of all 3 axes (pitch, roll, yaw) • Compares pilot inputs with gyroscope inputs, if there is a discrepancy (caused by air turbulence for example) correct flight Absolute Minimum Requirements • New system will successfully emulate the old system ON THE GROUND • New system will be lower in total cost than the old system
