All Questions

 Question: If mach number is 36 then what is the wing diverges in swept forward and swept backward aircrafts? By: Ashok kumar     Date: 2012-11-26 Answer: First of all, I am unable to understand the question. Forward swept wings have a divergence speed which is less than the sweptback wing. Where did you get this Mach number 36? By: Prof. C. Venkatesan     Email: ashokb2119@gmail.com     Date: 2012-12-07

 Question: how i have to start reading of aero elasticity ? in which order i should i have to start ? By: raja     Date: 2013-08-28 Answer: In the same order as the lectures. By: Prof. C. Venkatesan     Email: skyforads@gmail.com     Date: 2013-09-01

 Question: after greetings! in aircraft what are all the components comes under linear and non linear? please list out both linear and non linear aero elasticity issues? your explanation is superb! we are very lucky to have like you sir thank you. By: raja     Date: 2013-09-07 Answer: The non-linearities can arise from structural or from aerodynamic aspects. In structural aspect, the non-linearity can be due to: (i) geometric non-linearity (strain-displacement relation is non-linear) or material non-linearity (stress-strain relation is non-linear). In aerodynamics, the transonic problems are non-linear and also in subsonic case, if the flow over the airfoil has dynamic stall effects, then the problem is non-linear. In this lecture series, we have addressed only linear aeroelasticity problems. By: Prof. C. Venkatesan     Email: skyforads@gmail.com     Date: 2013-09-17

 Question: what is the main difference between aeroelastic tailoring and composite materials used in aircraft structures ? I\'m Little bit confused please clarify. Thank You Professor.. By: raja     Date: 2014-08-09 Answer: Composite materials can be used in the construction of the structure to obtain the required sectional properties (like bending and torsion stiffness properties) of the aircraft wing/ rotor blade etc. This may help in improving the aeroelastic behaviour of the wing. This is known as aeroelastic tailoring using composite materials. You can also use smart structure construction to improve the aeroelastic characteristics of the lifting surface. This can be called aeroelastic tailoring by smart structure concept. By: Prof. C. Venkatesan     Email: skyforads@gmail.com     Date: 2014-08-15

 Question: what is the main difference between aeroelastic tailoring and composite materials used in aircraft structures ? I\'m Little bit confused please clarify. Thank You Professor.. By: raja     Date: 2014-08-09 Answer: I have already given the answer for the same question once. I do not know why this question is being sent again and again. By: Prof. C.

 Question: IF YOU HAVE THE SOFT COPY OF THE SHORT NOTES ON COMPUTATIONAL METHODS IN AEROELASTICITY By:     Date: 2015-03-09 Answer: No I do not have a soft copy. By: Prof. C. Venkatesan     Email:     Date: 2015-03-11

 Question: sir, How to describe the transfer of in-flight airloads carrying on a wing skin to the fuselage in a systematic manner? By:     Date: 2015-11-17 The co-ordinator will post his answer
