Title: Flight Test Engineering
1Flight Test Engineering
2Why Flight Test ?
- Adequate replication on the ground of flight
conditions is often impractical - Particular flight conditions may be
insufficiently well defined to be simulated - Almost all aircraft incorporate many system whose
interactions are complex - Discrepancies between actual flight behavior and
predicted. Flight test data is essential to
improve accuracy of the models and simulation.
Flight Test is required to prove that the
man/machine combination can achieve the desired
performance.
3Nature of Flight Test
- Inherently Hazardous
- New configuration unproven system at the edge
and beyond of flight envelope. - Explore the most critical configuration and
failure cases of system.
- Expensive
- Requires instrumentations, infrastructure,
special maintenance of test vehicle, test area,
specific weather conditions and qualified people. - Involving many parties.
- Crew readiness
- Hazard assessment
- Safety review
- Extensive preparation and careful planning.
- Minimize flight hour
4General Approach of Flight Testing
Testing in operationally representative condition
in a controlled, incremental manner with critical
parameters monitored via appropriate
instrumentation.
- Starting from less hazardous and gradually
towards more hazardous case - Comparison between test results and prediction
- Explore aircraft envelope to ensure that aircraft
meets requirements at the most critical
conditions. - Testing in a known and controlled condition
(suitable weather, low air traffic density,
flight test instrumentation, safety equipments
and dedicated test support)
5Type of Flight Test
- Experimental Flight Test
- Research and Development purposes
- Development and Certification Flight Test
- Demonstration for the purpose of showing
compliance with design objective and/or
airworthiness requirement. - Must be performed using representative aircraft,
proven instrumentation and test maneuver as per
requirements. - Production Flight Test and Flight Test After
Maintenance - Testing of series aircraft to ensure correct
installation/maintenance within the established
limitation
