IRON BIRD : | Photographs | -
Real-time hardware-in-loop test facility enables integration, ground testing and clearance of IFCS
- Evaluates subsystem, open loop, closed loop, failure mode and pilot in the loop levels of IFCS.
- Progressive `DFCC interfaces using stimulated pilot controls, inertial & air data sensors, actuators followed by interfacing with actual LRUs.
- Static and dynamic response of control laws in a stand-alone mode and with
stimulated or real actuators interfaced
- Power-on delays among four channels of DFCC during startup, power interruptions during changeover from ground to aircraft power supply and extreme voltage power supply to DFCC and Hydraulic System failure conditions.
- Pilot acquaintance with failure mode warning displays and aircraft performance in flight
- Pilot confidence build up on performance and reliability of IFCS by fault free test flights
with aircraft standard cockpit controls & displays, DFCC, actuators, hydraulic system, DHEU and under carriage
- Real time acquisition of analog, discrete, RS422, MIL-STD-1553 and CCDL data transmitted by DFCC
| | | - Cockpit with aircraft standard pilot controls, warning panels
and Multi Function Displays
- Stimulated Avionic systems of Mission Computer, Inertial Navigation System and Utility Systems Management System
- Computer generated realistic display of under visual cues and HUD symbology.
- Real-time data acquisition facility from the MIL-STD-1553 data bus
- Real-time digital computer updating aircraft dynamics at every 6.25 msec
- programmable analog with discrete and digital signal interface facility
- six degrees of freedom aircraft flight dynamics model
- integrated models of landing gear, engine and atmosphere dynamics and
- inverse airdata system model to generate port pressures of airdata probes
- Engineering Test Station to integrate all quadruplex interfaces of DFCC
- interfacing stimulated or real LRUs
- real time serial communication link for online
- accessing of DFCC memory, signal monitoring and data
