Book excerpt: The technological problems and practical engineering aspects associated with the design and testing of a homing parchute system are presented. This device consists of a solid, flat, circular parachute with an open gore which provides a horizontal thrust component, causing the parachute to glide. An electromechanical control system employing a direction-finding antenna is used to control the orientation of the open gore with respect to a ground transmitter so that the parachute glides toward the transmitter.

This book was released on 1969 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations are presented and evaluated for estimating the wind effect on the approach path and descending orbit of gliding parachute systems with non-proportional automatic homing control. Exact equations are presented for determining certain characteristic features of the descending orbit. Iteration equations are presented incorporating homing simulation for calculating points at equal time intervals along the ground track. The control response time, effect of deployment position, and impact position probability are discussed. An empirical equation for the radius of the circle of equal probability as a function of turning radius, wind velocity, and system velocity is presented. A parametric analysis of the equations is given for systems with glide ratios from 2.0 to 3.0 and turning radii of 75 ft and 100 ft in winds of from 4 to 32 fps. The analysis shows that accuracy is more dependent on high glide ratio than on turning radius. (Author).

Download or read book Uniform Wind Trajectories of a Gliding Parachute Using Azimuth Homing written by Arthur L Murphy (Jr) and published by . This book was released on 1972 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional parachute systems must be launched at the lowest possible altitude in order to insure acceptable accuracy. Due to the need for such critical release point positioning, delivery aircraft are required to maneuver in a restrictive and generally unfavorable air space. This is particularly true for the majority of resupply missions necessitating an airdrop. It is, therefore, of interest to consider advanced airdrop techniques, with the objective of relaxing launch constraints while maintaining or improving drop zone accuracy. This paper is concerned primarily with the trajectory or flight path aspects of gliding parachute development. The presentation is analytic in scope, producing from geometric constraints imposed by the guidance scheme, a class of closed form solutions specifying trajectories and launch criteria.

Book excerpt: This document serves as the third revision of the USAF Parachute Handbook which was first published in 1951. The data and information represent the current state of the art relative to recovery system design and development. The initial chapters describe representative recovery applications, components, subsystems, material, manufacture and testing. The final chapters provide empirical data and analytical methods useful for predicting performance and presenting a definitive design of selected components into a reliable recovery system.
Download or read book Parachute Recovery Systems written by Theo W. Knacke and published by . This book was released on 1992 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.

Available in PDF, EPUB and Kindle. Book excerpt: The planar trajectory of a [sic] Azimuth Homing gliding parachute maneuvering in a uniform wind field is presented. The kinematics of the motion is discussed generating two first order differential equations which are separated producing an expression involving only position coordinates. A change of variables is introduced and exact solutions obtained by direct integration. The resulting trajectories fall into two categories to their Target Seeking or Orbital characteristics. Flight paths in the Target Seeking domain are shown to be convergent when the system has a wind penetration capability. The corresponding velocity state at target fly-over is a minimum. The family of Target Orbiting solutions are shown to produce trajectories hich are captured about the target in Elliptic Spirals.

Download or read book Trajectory Analysis of a Radial Homing Gliding Parachute in a Uniform Wind written by Arthur L. Murphy (Jr.) and published by . This book was released on 1971 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two dimensional trajectory of a radial homing gliding parachute in a uniform wind is presented. The kinematics of the motion is discussed generating two first order differential equations which are separated and solved by direct integration. The resulting expression functionally relates the radial position of the parachute to the instantaneous value of the azimuth angle. Utilizing this result, an exact solution for time in terms of space coordinates in then obtained. From geometric considerations the angular motion along the azimuth direction is found to be stable when the system is flying into the wind.
