Flight Tests
The ADAG research group has been working on the flight test campaign of G97 light aircraft. All aspects regarding JAR-VLA certification procedures have been object of research. Accurate and detailed analysis of flight test maneuvers have been performed and comparison with numerical prediction (stall speed) have been done. All G97 performances have been measured.
Flight tests on a DG400 sailplane are also reported.
In that campaign a in-house-developed parameter estimation method has been validated.
Detailed study of low-cost and good accuracy sensors for
flight parameters acquisition have been carried out. Set up of a good and efficient acquisition system to be
used on a small radio-controlled model is under development. Study
of the aircraft aerodynamic characteristics estimation through flight
maneuvers measurement is under development
Certification
- Instruments, sensors and acquisitions systems for light aircraft flight tests
- Flight data analysis, performance, static and dynamic stability evaluation
- UAV and Radio Controlled model flight instrumentation (measurement and control)
Flight Tests
- Performance and flying qualities evaluation
- Manoeuvers analysis and comparisons with numerical results
In recent years several general techniques have been developed for the determination of the characteristics of physical systems, based on their measured responses (time histories of some observed variables). Part of ADAG research is devoted to one of these techniques known as Maximum Likelihood Method (MLM). It has been applied to airplane flight data. Given the equations governing the aircraft flight, the MLM allows the estimation, i.e. extraction, of the parameters included in the mathematical model directly from flight data. Linearized aircraft equations of motion are implemented in the performances and dynamic behavior prediction code MeMaV , developed at DIAS. MeMaV code has been validated by case studies in which flight characteristics are known.
