PROJET 17: OPTIMISATION OF AIRCRAFT FLIGHT TRAJECTORIES
In this project, realized in collaboration with the Romanian Airline TAROM in Romania, aircraft flight trajectories are optimized for their use by pilots in the real flight of aircraft.

PROJECT 16: FLIGHT MANAGEMENT PERFORMANCE OPTIMISATION II
In this project, realized in collaboration with CMC Electronics-Esterline, the main objective is to optimize the vertical and horizontal path of the aircraft within the Flight Management System by taking into account the Required Time of Arrival, the wind grids and meteorological conditions. The main motivation of the project is to reduce overall carbon emissions and flight costs. This project is funded by the Green Aviation Research Development Business Led Network GARDN in its second round.

PROJECT 15: CANADA RESEARCH CHAIR IN TECHNOLOGIES FOR AIRCRAFT MODELING AND SIMULATION
The Chair’s activities, that started on 1st of January 2011, and are taking place until 1st of January 2025 are revolving around two main research axes: (1) aircraft and helicopter flight dynamics and control; and (2) active control technologies for deformable aircraft.

In the first axis, new modeling and simulation methodologies for aircraft and helicopter flight dynamics and control are designed. Using flight test data, non-linear optimization algorithms are developed to identify and validate aircraft and helicopters.

In the second axis, the LARCASE team is using geometric data to analyze aircraft stability. The shape of wings and other geometric surfaces of autonomous aerial systems are modified using active control systems, to enhance the aerodynamic performance of aircraft.

The subsonic blown down wind tunnel Price-Païdoussis, the aircraft research flight simulator, and an unmanned aerial system UAS designed and manufactured by Hydra Technologies (please see the next photo) are used in axes 1 and 2 of the Canada Research Chair.

The UAS was obtained with research funds from Canadian Foundation for Innovation CFI, Ministère du Développement économique, innovation et exportation MDEIE and Hydra Technologies. The research performed on the UAS will be realized in collaboration with Hydra Technologies in Mexico.

PROJECT 8: CRIAQ 7.1 - CONTROLLER DESIGN AND VALIDATION FOR LAMINAR FLOW IMPROVEMENT ON A MORPHING RESEARCH WING - VALIDATION OF NUMERICAL STUDIES WITH WIND TUNNEL TESTS
In this CRIAQ 7.1 project lauched during the second CRIAQ round, called Improvement of laminar flow on a research wing, the laminar to turbulent flow transition on a wing with a flexible skin on its upper surface was controlled and therefore delayed by use of kulite pressure sensors and smart actuators in a wind tunnel. This project was realized in collaboration with Thales Avionics, Bombardier Aerospace, École Polytechnique and LAMSI team at ETS.

The LARCASE team designed, integrated and validated a controller for the transition delay on a morphing wing, which changed its shape, by use of Smart Material Actuators and pressure sensors.

PROJECT 7: AEROSERVOELASTIC INTERACTIONS STUDIES FOR THE F/A-18 SRA, ATW AND AAW - VALIDATION WITH FLIGHT FLUTTER TESTS (PROJECT SINCE 1998)

The aeroservoelasticity works were realized in collaboration with NASA Dryden Flight Research Center (DFRC) in three well known aeroservoelasticty projects using the flight data for the following airplanes: F/A-18 Systems Research Aircraft (SRA), the Aerostructures Test Wing (ATW) and the F/A-18 Active Aeroelastic Wing (AAW). The industrial collaborator in this project was Mr Marty Brenner from NASA DFRC. Other collaborators from NASA DFRC between 1998 and 2003 were: Dr Kajal Gupta, Mr Tim Doyle, Mr Ed Hahn, Mr Roger Truax andt Dr Can Bach.

These flight test data were used for:
  1. the validation of new methods of conversion of aerodynamic forces from the frequency domain into the Laplace domain,
  2. the design of new algorithms for the interactions between aircraft rigid, elastic and control modes and
  3. the elaboration of new parameter estimation methods by use of fuzzy logic, neural network, etc.


This research work is mainly funded by FQRNT and NSERC in the period of time 1998-2002 and since 2002 by MDEIE and NSERC.

Video on the aeroservoelastic interactions analysis on the F/A-18 SRA

This video shows the results of the research on the interaction of rigid, control and elastic modes on the F/A-18. There are two parts in this video. In the case when this interaction is not well analyzed, the aircraft has a non-realistic and unstable behaviour. In the case when the interaction is well done, the aircraft becomes stable. For details on this research, please see article 10 in the section 'Accepted Publications''. Dr Lucian Grigorie and Dr Adrian Hiliuta reaized this video.

Vidéo du code concu au LARCASE pour le calcul des dérivées de stabilité en se basant sur la géometrie de l'avion

This film, done by the Master student Dumitru Popescu from LARCASE, shows the results obtained by our in-house code, designed and developped during 5 years, in Matlab, based on the references from US Datcom and other more recent references in aerodynamics. We are using for this film, the geometrical data of a non-confidentail airplane. It can be seen that based on a minimum amount of geometrical aircraft data, the aerodynamic lift, drag and moment coefficients as well as their derivatives are very rapidly calculated.

For this project, its results were validated with flight test data on the Hawker 800 XP. This work is used for the preliminary design of aircraft (and of their components) based on the minimum of geometrical data.

PROJECT 1: IMPLEMENTATION OF GLOBAL MODEL PARAMETER ESTIMATION TECHNOLOGY FOR THE BELL 427 - VALIDATON WITH FLIGHT TESTS
In the CRIAQ project 3.4, the LARCASE team in collaboration with NRC and BHT teams validated a methodology to analyze the aerodynamic critical cases for helicopters and to conceive a global model for the B-427 helicopter. These cases were the following: auto-rotation, transition, close manoeuvres to the flight envelope corners, ground dynamics, hover, forward flight and ground reaction which represent challenges for the experts in the parameter estimation methods. This methodology was validated by flight tests at BHT where was used for level D high fidelity simulator certification according to FAA rules. The industrial leaders are Mr Ed Lambert and Mr Joey Seto (Bell Helicopter Textron) and Mr Ken Hui (IAR-NRC)

The main avantage of this new methods resulted in an important reduction of flight test number, that reduced the cost and the time needed for the development of new helicopters. This new approach allowed the reduction of approximately 60% of the development cycle. This project was funded by Bell Helicopter Textron and CRIAQ. Research on this project started in 2003 and ended in 2009.
