Aircraft Structures - I

By Prof. Anup Ghosh | IIT Kharagpur

Learners enrolled: 1774

ABOUT THE COURSE:
This course is an introduction for the analysis of aircraft structures. It bridges together the basic solid mechanics with applications to aerospace structures. The course starts with the introduction to the basic details of type of structures used in aircraft construction. It is followed by an introduction to the estimation of loads on wing, fuselage and landing gear. Principle of stressed skin structure and indeterminate structures are covered next. Theory of elasticity will be introduced later for analysis of problems related to aerospace structures.

INTENDED AUDIENCE : Aerospace, Mechanical, Civil, Naval Architecture.

PREREQUISITES : Basic Solid Mechanics

INDUSTRIES SUPPORT : ISRO, DRDO, CYIENT, TATA Lockheed Martin Aerostructures Ltd., Mahindra Aerospace, HAL, Raj Hamsa Ultralights.

Instructor bio

Prof. Anup Ghosh

IIT Kharagpur

In the last few years I have completed guidance of 3 Ph. D. student and 4 more students are continuing at present. In this process we have explored and studied the nonlinear behaviour of laminated composite laminates in association with the interdigitated smart composite structures. The study also includes the hygrothermal effect on the geometrically nonlinear vibration of AFC actuated composite structures. It includes the active vibration control of smart laminated composite plates. An UAV laboratory has been developed in recent years in our department. This laboratory is equipped with all possible modes of UAV fabrication facility including fibre reinforced laminated composite structures using vacuum assisted resin transfer moulding procedure. One more laboratory has been set up for complete characterization of laminated composite in the department of Chemical Engineering under the DST funding. Five major sponsored R&D projects have been completed. In a nutshell any research related to the structural analysis and experiments of aircraft related structures may be pursued. It is intended to emphasize the area related to the development of MAV and UAV in near future.

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
