Description

This course provides an overview of aircraft structural external loads analysis including: criteria, design, analysis, fatigue, certification, validation and testing. It covers FAR 23 and FAR 25 airplane loads requirements. However, the concepts may be applicable for military structural requirements. Loads calculations examples using BASICLOADS software will be demonstrated throughout the course week. A copy of BASICLOADS software will be provided to attendees.


Includes instruction, a course notebook, a copy of BASICLOADS software, refreshments and lunches. The course notes are for participants only and are not for sale.

**U.S. Federal Employee Discount: This course is available to federal employees at a 10% off the registration fee. To receive the federal employee discount, enter the code fgvt116 when registering. Please note that you must validate your eligibility to receive this discount by entering your U.S. government email address ending with .gov or .mil.

Highlights

  • Overview of data requirements—aerodynamics, mass properties, stiffness, control systems and propulsion
  • Certification requirements—methods of compliance and FAR23 and FAR25 loads requirements
  • Structural design airspeeds derivations—construct flight envelope
  • V-n diagrams—calculation of maneuvering load factors, gust load factors, construct V-n diagrams
  • Maneuver loads—balanced maneuvers, abrupt pitch maneuvers, roll maneuvers, yaw maneuvers and engine-out maneuvers
  • Gust loads—gust formula, discrete tuned 1-cos gust, PSD gust, vertical, lateral and head-on gust
  • Ground loads—landing, taxi, ground handling, static and dynamic loads and landing gear drop test
  • Airframe loads—wing, horizontal tail, vertical tail, fuselage, control surfaces and flaps
  • Fatigue loads—certification requirements, mission requirement, exceedance curve, gust and maneuver fatigue loads
  • Loads testing – flight loads validation, ground calibration, static limit and ultimate test and fatigue loads test
  • Loads calculations using BASICLOADS software throughout the course

  • How to calculate basic loads
  • The various types of loads conditions—flight maneuvers, gust conditions, landing, ground handling, fatigue
  • The flight and ground testing requirements

Course Outline

Day One

  • Introduction and overview of the course
  • Basic aerodynamics overview
  • Certification requirements (FAR 23, FAR 25, EASA, MIL-SPECS)

  • Structural design airspeeds derivations (maneuver, gust penetration, cruise, dive, flap extended, design-airspeeds code)
  • V-n diagrams (maneuver and gust load factors calculations, V-n diagram code)

Day Two

  • Introduction to external loads (definitions, static vs. dynamic, flutter, loads classifications)
  • Steady maneuvers (wind-up turn, pull-up, balancing tail loads derivations, bal-maneuver code)
  • Pitch maneuvers analysis (abrupt pitch up, abrupt pitch down, checked pitch)
  • Roll maneuver analysis

Day Three

  • Yaw maneuver and engine out analysis
  • Basic structural dynamics overview

  • Landing loads analysis (one wheel, two wheel, three wheel, landing code)
  • Ground handling maneuver loads analysis (taxi, ground turn, nose-wheel yaw, braking, towing, jacking, ground-loads code)
  • Fatigue loads analysis (normal operational conditions, missions, load spectra)

Day Four

  • Wing loads analysis (design wing conditions, wing-load code)
  • Horizontal tail loads analysis (HT loads certification requirements, design HT conditions)
  • Vertical tail loads analysis (VT loads certification requirements, design VT conditions)
