Summary of Spin Technology as Related to Light General-aviation Airplanes
Author: James S. Bowman
Publisher:
ISBN:
Category : Airplanes
Languages : en
Pages : 44
Book Description
A summary was made of all NASA (and NACA) research and experience related to the spin and recovery characteristics of light personal-owner-type general-aviation airplanes. Very little of the research deals with light general-aviation airplanes as such, but many of the airplanes and models tested before and during World War II were similar to present-day light general-aviation airplanes with regard to the factors that are important in spinning. The material is based mainly on the results of spin-tunnel tests of free-spinning dynamically scaled models of about 100 different airplane designs and, whenever possible, includes correlation with full-scale spin tests. The research results are discussed in terms of airplane design considerations and the proper use of controls for recovery.

The Effect of Variations in Moments of Inertia on Spin and Recovery Characteristics of a Single-engine Low-wing Monoplane with Various Tail Arrangements Including a Twin Tail
Author: Anshal I. Neihouse
Publisher:
ISBN:
Category : Airplanes
Languages : en
Pages : 50
Book Description
Results of an investigation made in the Langley 15-foot free-spinning tunnel of the effects of variation of the moment of inertia of a research model representative of a present-day trainer or a four-place cabin monoplane are presented. Eight different wing arrangements and four different tail arrangements, including a twin tail, were tested. The moments of inertia about the three airplane axes were increased or decreased by a constant percentage and the results were compared. These results were also compared with results previously presented for variation of the airplane relative density.

Analytic Prediction of Airplane Equilibrium Spin Characteristics
Author: William Mansfield Adams
Publisher:
ISBN:
Category : Equations of motion
Languages : en
Pages : 52
Book Description
The nonlinear equations of motion are solved algebraically for conditions for which an airplane is in an equilibrium spin. Constrained minimization techniques are employed in obtaining the solution. Linear characteristics of the airplane about the equilibrium points are also presented and their significance in identifying the stability characteristics of the equilibrium points is discussed. Computer time requirements are small making the method appear potentially applicable in airplane design. Results are obtained for several configurations and are compared with other analytic-numerical methods employed in spin prediction. Correlation with experimental results is discussed for one configuration for which a rather extensive data base was available. A need is indicated for higher Reynolds number data taken under conditions which more accurately simulate a spin.
