RATIONALE:

The aircraft industry makes great demands upon its materials. Not only must designs be efficient and as light as possible, but they must also ensure that failure in flight does not occur on account of the almost certain tragic consequences. To ensure reliable operation, the design must also include maintenance in the form of inspection and repairs due to corrosion or cracking due to metal fatigue. A knowledge of aircraft materials is of fundamental importance to those engaged in aircraft maintenance and modification.


SYNOPSIS:

This course provides a broad outline of the characteristic properties and behaviour in service of the commonly used aircraft materials, with particular emphasis on airframe materials. This knowledge allows an understanding of the consequences of the use of incorrect material for component replacement and provides a basis for appreciating the inspection procedures used as part of the maintenance schedule. Some newer materials likely to find more widespread use in aircraft in the future are also briefly covered.


OBJECTIVES:

On completion of this course, students should be able to:

  • understand the characteristic properties, behaviour in service and typical applications of commonly used aircraft materials;

  • describe the common mechanical test procedures used to assess the performance of materials used in aircraft construction;

  • apply technical and conceptual skills in the application of mechanical test results to aircraft materials;

  • describe the various non destructive testing techniques and the application of such techniques in aircraft maintenance.

    IMPORTANT ASSESSMENT INFORMATION

    1. Attendance requirements:
      It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.
    2. Requirements for students to complete each assessment item satisfactorily:
      To complete the practical component satisfactorily, students must submit, by the due date, a practical report which meets the requirements of the assessment scheme.
    3. Penalties for late submission of required work:
      A CMA submitted after the due date will not be marked if the results and answers have been released.
    4. Requirements for student to be awarded a passing grade in the course:
      To be assured of receiving a passing grade a student must submit all of the summative assessment items, achieve at least 40% in the examination and at least 50% of the available weighted marks for the summative assessment items.
    5. Method used to combine assessment results to attain final grade:
      The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.
    6. Examination information:
      In a Closed Examination, candidates are allowed to bring only writing and drawing instruments into the examination.
    7. Examination period when Deferred/Supplementary examinations will be held:
      Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course.
    8. University Regulations:
      Students should read USQ Regulations 5.1 Definitions, 5.6. Assessment, and 5.10 Academic Misconduct for further information and to avoid actions which might contravene University Regulations. These regulations can be found at the URL http://www.usq.edu.au/SECARIAT/calendar/Part5/ or in the printed version of the current USQ Handbook.

    ASSESSMENT NOTES

    1.In accordance with University's Assignment Extension Policy (Regulation 5.6.1), the examiner of a course may grant an extension of the due date of an assignment in extenuating circumstances.
    2.The Faculty will normally only accept assessments that have been written, typed or printed on paper-based media.
    3.The Faculty will NOT accept submission of assignments by facsimile.
    4.Students who have undertaken all of the required assessments in a course but who have failed to meet some of the specified objectives of a course within the normally prescribed time may be awarded the temporary grade: IM (Incomplete - Make up). An IM grade will only be awarded when, in the opinion of the examiner, a student will be able to achieve the remaining objectives of the course after a period of non-directed personal study.
    5.Students who, for medical, family/personal, or employment-related reasons, are unable to complete an assignment or to sit for an examination at the scheduled time may apply to defer an assessment in a course. Such a request must be accompanied by appropriate supporting documentation. One of the following temporary grades may be awarded IDS (Incomplete - Deferred Examination; IDM (Incomplete Deferred Make-up); IDB (Incomplete - Both Deferred Examination and Deferred Make-up).
