MODEL & MINIATURE AIRCRAFT DESIGN xx MODEL & MINIATURE AIRCRAFT Longitudinal stability explained. A close look at model aircraft stability problems as applied to a modern F1B Wakefield free-flight rubber model. The long and short of it. How a model aircraft's moment arm affects its flight characteristics. The neutral point. Understanding and locating the neutral point of an aircraft which relates to its stability. Fit for action. Trimming a scale model for successful flight begins on the drawing board. Where's the CG. Center-of-gravity on an indoor Pennyplane. Part 1. Concept of margin of stability. Spiral stability and the bowl effect. Part 1. Importance of full spiral stability in the performance of free-flight models and radio-control sailplanes. Junior flight. Using a 3"x5" file card to demonstrate how an airplane flies. Where's the CG. Part 2. Critical components of aerodynamic stability. Spiral stability and the bowl effect. Part 2. Flight dynamics during circling flight. How spiral stability is affected in spirally unstable aircraft. Device for locating the center of gravity of a model airplane. Vertical tail size for models. Part 1. Combined influence of vertical tail size and total effective dihedral on a model's stability in flight. Vertical tail size for models. Part 2. Tail size, turning trim, wing dihedral, and effective dihedral. A primer on aerodynamics. A master modeller gives advice on how to select or modify a sound design. How to trim a model. Applying elementary aerodynamic concepts will help you design (or improve) your model airplane. Part 1. How to trim a model. Part 2. Centrifugal force and its role in model aircraft design and flight. Aerodynamic investigations. Using an electric-powered model aircraft to help solve aerodyanmic problems and improve performance. Part 1. Wing design parameters. Aerodynamic investigations. Part 2. Horizontal tails, winglets, and force arrangements. Structural design of model aircraft. Part 1. Structural design of model aircraft. Part 2. Model design using spreadsheets. Includes a sample spreadsheet file which shows the calculations for a conventional aircraft with segmented wing panel. Aeodynamics discussion considers the pitch stability and balancing of R/C aerobatic model airplanes. Lofting, a technique of drawing shapes that will result in smooth outside form. Use it to generate the formers for any cross-section fuselage and the ribs for a tapered wing. Can also be used to design cowls and canopies. Go one better. Ways to improve your model airplane's performance. Ideas on the development of an aileron-controlled power sport model suitable for mild aerobatics. Adjustable jig for balancing model aircraft of various sizes. Tip on using a spring balance to locate the center of gravity of a model airplane. Designing your own scale model aircraft. Modeling a "Tipsy Junior" is used to illustrate the process. Part 1. Scale and size of the model. Designing your own scale model aircraft. Part 2. Structure. Tip on adjusting a model aircraft to the correct center of gravity. Designing your own scale model aircraft. Part 3. More scale model airframe construction techniques. | |||||||||
