Book excerpt: A theoretical structural dynamic model of a MER (Multiple Ejection Rack), based upon BERNOULLI Pitch and yaw bending deflections and torsional rotation, is developed. Six-degree-of-freedom store ejection conditions are predicted. Sample computations were made for a M-117 bomb and constant aircraft pull-up rates corresponding to up to a 3.9 'g' normal acceleration. The computations were for the second, fourth, and sixth bombs dropped in the normal release sequence from an A-7D right wing center pylon station. Ejection velocities computed do not deviate more than 15% from the rigid case. Ejection pitching and rolling rates are affected more significantly by flexibility. However, the pull-up maneuver alone affects the ejection conditions to a greater extent than flexibility for most ejection variables and 'g' values greater than 2.

Book Synopsis An Estimate of the Effect of MER (Multiple Ejection Racks) Structural Dynamics on Store Separation by :
Download or read book An Estimate of the Effect of MER (Multiple Ejection Racks) Structural Dynamics on Store Separation written by and published by . This book was released on 1974 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural flexibility has long been suspected as being a factor affecting the ejection phase dynamic response of stores. After hook opening, in-carriage loads, associated with a released store, and an ejection recoil force deflect the MER beam away from its initial position. This in turn leads to a lower ejection velocity, lower ejection pitch rate, and an induced rolling moment. A theoretical structural dynamic model is based upon 'Bernoulli' pitch and yaw deflections and torsional rotation of the MER beam; wing, pylon, hanger, shoulder pad, and ejector unit deformations are neglected. Detailed development for the present report is confined to the pitch plane bending and store pitch dynamics case. For small pitch angles a linear set of kinematic and dynamic equations for the store ejection phase is obtained. Sample computations are given for two stores and constant aircraft pull-up rates.

Download or read book Self-compensating Store Ejection written by Raymond R. Maestri and published by . This book was released on 1974 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report concerns the concept of a continuously adjustable ejector system which accounts for the aircraft flight condition and ejects a store with an initial angular rate and linear velocity that results in a safe, repeatable, predictable nearly ballistic trajectory throughout the aircraft/store carriage envelope. The concept is especially important in the supersonic regime where the aerodynamic forces in the disturbed flow field control the initial trajectory. (Modified author abstract).
Book Synopsis Extension of the Method for Predicting Six-Degree-of-Freedom Store Separation Trajectories at Speeds Up to the Critical Speed to Include a Fuselage with Noncircular Cross Section. Volume II - Users Manual for the Computer Programs by : Frederick K. Goodwin
Download or read book Extension of the Method for Predicting Six-Degree-of-Freedom Store Separation Trajectories at Speeds Up to the Critical Speed to Include a Fuselage with Noncircular Cross Section. Volume II - Users Manual for the Computer Programs written by Frederick K. Goodwin and published by . This book was released on 1974 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed instructions are presented for using two computer programs which calculate the six-degree-of-freedom trajectories of external stores which are separated from fighter-bomber type aircraft at speeds up to the critical speed. Single and multiple store configurations can be handled by the programs. The first program calculates the source distributions which represent the volume distributions of the fuselage, store(s), and ejector rack if one is present. The second program uses a lifting-surface theory to determine a vorticity distribution which represents the wing and pylon loading and calculates the trajectory of the ejected store. This report describes the two programs, presents instructions for preparing input for the programs, describes the output from each program, and presents sample cases.

Book Synopsis Aircraft Weapon System Compatibility and Integration by :

Book excerpt: Weaponry is a central factor in any kind of military activity. The incorporation of weapon systems into aircraft and their integration and satisfactory operation is a topic of major importance to armed forces and manufacturers of weapons and aircraft alike. The scope of this symposium was to critically review the overall state-of-the-art in aircraft weapon system compatibility and integration and to illuminate possible paths for future development and provide beneficial ideas and experience. Sessions dealt with the following topics: Theoretical methods and modelling techniques, Experimental and flight test techniques, Integration processes and programmes, Addressing future challenges. This symposium produced many excellent papers providing broad coverage of the weapons integration issues. There were many common threads with regard to the analysis, wind tunnel testing, and flight testing. Computational fluid dynamics (CFD) is proving to be a useful technique; wind tunnel testing is very important in the weapons integration process; but, flight testing has to be the final phase of the weapons integration process. This symposium produced a level of cohesiveness between the analysts and testers; however, full agreement as to the mix of analysis and testing did not evolve. In order to reduce the cost of weapon integration, certification, clearance, and flight testing, weapon integration analytical techniques, including CFD and wind tunnel testing, and flight testing need to become more of an integrated process. The knowledge gained and information shared at this symposium should assist the participants in developing a more integrated process in order to provide NATO nations with fully integrated weapon systems at an affordable price.
