Reference number : GC-2017-Q4-00565, amendment number : , agreement type : G, recipient legal name : Fawaz, Zouheir (Ryerson University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : The project industrial partner, Airvinci, is developing a coaxial rotorcraft with a ducted fan in both manned and_x000D_
unmanned types. Increasing the payload fraction of the rotorcraft is Airvinci's major objective as it would_x000D_
increase fuel economy and maneuverability. As a result Airvinci desires a composite airframe that meets all_x000D_
regulations according to FAR part 27. The composite airframe will need to be optimized to endure all flight_x000D_
loads as well as impact load dissipation during the landing phase. The two main objectives of the proposed_x000D_
project are:_x000D_
1.Direct Replacement of an existing steel spaceframe with composite equivalent._x000D_
2.Design of an optimized impact reducing composite airframe_x000D_
The research effort will therefore focus on the following:_x000D_
1.Non-linear Explicit Dynamic Structural Analysis_x000D_
The airframe will need to be crashworthy according to FAR part 27 standards. Therefore, it will be required to_x000D_
show that the airframe will not deform significantly or will springback under dynamic loads. Traditional FE_x000D_
models utilize linear solvers for static analysis and small displacements. For an accurate estimation towards the_x000D_
airframe's crashworthiness and energy absorbing capabilities of the landing skids, a Non-linear model explicit_x000D_
model will be required. The nonlinear model will allow for more complex failure modes as well as dynamic_x000D_
analysis. An explicit solver will allow for simulating the landing._x000D_
2.Design Optimization_x000D_
The anisotropic properties of composites allow for a great deal of tailoring towards the design loads. Using a_x000D_
combination of the packages available in ANSYS it is possible to determine the directions of the plies as well_x000D_
as their stacking sequence. The resulting design will also be optimized for manufacturing to avoid complex_x000D_
