Rockets for Spin Recovery

Book Description
Consideration is given to use of a jet-reaction device for emergency spin recovery. Brief tests made in the Langley 20-foot free-spinning tunnel on a dynamic scale model with a reaction rocket fired rearward from the inboard wing tip (right wing tip in a right spin) indicated that such a device would be effective for recovery from an uncontrollable spin.
Comparison of Model and Full-scale Spin Recoveries Obtained by Use of Rockets

Book Description
The results of the tests indicated that the recoveries of the model were in good agreement with those of the corresponding airplane, and for the design and loading tested, wing-tip rockets quickly terminated the spin. For the spins obtained, left- or right-wing-tip rockets appeared to be equally effective for recoveries.

Book Description
state of the art in aeronautical engineering has been continually accelerated by the development of advanced analysis and design tools. Used in the early design stages for aircraft and spacecraft, these methods have provided a fundamental understanding of physical phenomena and enabled designers to predict and analyze critical characteristics of new vehicles, including the capability to control or modify unsatisfactory behavior. For example, the relatively recent emergence and routine use of extremely power- ful digital computer hardware and software has had a major impact on design capabilities and procedures. Sophisticated new airflow measurement and visualization systems permit the analyst to conduct micro- and macro-studies of properties within flow fields on and off the surfaces of models in advanced wind tunnels. Trade studies of the most efficient geometrical shapes for aircraft can be conducted with blazing speed within a broad scope of integrated technical disciplines, and the use of sophisticated piloted simulators in the vehicle development process permits the most important segment of operations—the human pilot—to make early assessments of the acceptability of the vehicle for its intended mission. Knowledgeable applica- tions of these tools of the trade dramatically reduce risk and redesign, and increase the marketability and safety of new aerospace vehicles.
Stresses Around Rectangular Cutouts in Torsion Boxes

Category : Boxes
Languages : en
Pages : 632
Book Description
A method is presented for calculating the stresses produced by rectangular cutouts of any size in torsion boxes. The problem is divided into a "box problem" and a "cover problem." The box problem is a special case of the general method of analyzing torsion boxes without cutouts. In the cover problem, simple shear-lag theory is used to obtain "key" stresses; the final distributions are obtained from these key stresses by means of simple rules or empirical distribution curves. Comparisons with the results from three series of tests in which the dimensions of the cutouts varied over a wide range are shown.
