NASA RESEARCH ON FLEXIBLE WINGS By Francis M. Rogallo NASA Langley Research Center SUMMARY Flexible wings are wings made of very loose or slack cloth whose configu- ration in flight is maintained by the combination of the aerodynamic forces and the reactions from the load suspension system. Such wings can be completely flexible_ or they may be stiffened in several ways to meet the requirements of particular applications. Wing planforms and the geometry of the load suspension system are also subject to wide variations. The overall spectrum of flexible wings investigated at the Langley Research Center is presented and the state of the art with regard to maximum lift-drag ratios obtained is defined for a wide range of wing configurations. Maximum lift-drag ratios above 3.0 were obtained on completely flexible wings; and for cylindrical-type flexible wings, values of lift-drag ratios up to 17.0 were obtained when the wing had small, tapered rigid leading edges. The flexible wings of most immediate interest are those with no structural stiffening because they have weight, volume, packing, and deployment character- istics potentially as good as those of conventional parachutes, but provide a stable and controllable glide with performance adequate for aerial delivery of cargo and personnel, for landing space capsules, boosters, or hypersonic air- craft, and as emergency wings for aircraft or aircraft escape systems. -

Powered Paraglider Longitudinal Dynamic Modeling and Experimentation
POWERED PARAGLIDER LONGITUDINAL DYNAMIC MODELING AND EXPERIMENTATION By COLIN P. GIBSON Bachelor of Science in Mechanical and Aerospace Engineering Oklahoma State University Stillwater, OK 2014 Submitted to the Faculty of the Graduate College of the Oklahoma State University in partial fulfillment of the requirements for the Degree of MASTER OF SCIENCE December, 2016 POWERED PARAGLIDER LONGITUDINAL DYNAMIC MODELING AND EXPERIMENTATION Thesis Approved: Dr. Andrew S. Arena Thesis Adviser Dr. Joseph P. Conner Dr. Jamey D. Jacob ii Name: COLIN P. GIBSON Date of Degree: DECEMBER, 2016 Title of Study: POWERED PARAGLIDER LONGITUDINAL DYNAMIC MODELING AND EXPERIMENTATION Major Field: MECHANICAL AND AEROSPACE ENGINEERING Abstract: Paragliders and similar controllable decelerators provide the benefits of a compact packable parachute with the improved glide performance and steering of a conventional wing, making them ideally suited for precise high offset payload recovery and airdrop missions. This advantage over uncontrollable conventional parachutes sparked interest from Oklahoma State University for implementation into its Atmospheric and Space Threshold Research Oklahoma (ASTRO) program, where payloads often descend into wooded areas. However, due to complications while building a powered paraglider to evaluate the concept, more research into its design parameters was deemed necessary. Focus shifted to an investigation of the effects of these parameters on the flight behavior of a powered system. A longitudinal dynamic model, based on Lagrange’s equation for adaptability when adding free-hanging masses, was developed to evaluate trim conditions and analyze system response. With the simulation, the effects of rigging angle, fuselage weight, center of gravity (cg), and apparent mass were calculated through step thrust input cases. -

Kites: Pioneers of Atmospheric Research
Chapter 6 Kites: Pioneers of Atmospheric Research Werner Schmidt, William Anderson Abstract Kites were essential platforms for professional exploration of the atmo- sphere for more than two centuries, from 1749 until 1954. This chapter details the chronology of kite-based atmospheric research and presents a brief examination of the well-documented scientific kiting based at the Royal Prussian Aeronautical Ob- servatory. Parallels are drawn between scientific kiting from then and contemporary power-generation kiting. Basic kite types of the time are presented and the design evolution from those towards advanced payload carriers is discussed. These include the Lindenberg S- and R-Kites, the latter of which featuring an effective passive de- power mechanism. The practices of launch and retrieval of kites and the components developed for this purpose are outlined, in particular those in use at the Meteorolog- ical Observatory Lindenberg. Their methods and techniques represented the state of the art after WWI and lay the groundwork for modern efforts at atmospheric energy extraction using kites. 6.1 Introduction The workhorse for performing tasks at altitude from the mid-1800s up until the ad- vent of the powered airplane in the early 1900s was often the humble kite. These tasks included aerial photography [3], manlifting for purposes of military surveil- lance [28], and although less widely declared, airframe development for later un- tethered, manned flight (most notably the Wright brothers’ wing warping kite of 1899 [18]). Kites were also indispensable in the development of wireless radio and telegraphy, in which kites were used by radio-pioneer and physicist Marconi to lift the first antennae to suitable altitudes for reception of messages transmitted via ra- Werner Schmidt Strengeweg 14, 26427 Holtgast/Utgast, Germany, e-mail: [email protected] William Anderson (B) Advance Paragliders, Uttigenstrasse 87, 3600 Thun, Switzerland, e-mail: [email protected] 95 96 Werner Schmidt, William Anderson dio [7].
