Hang Glider: Range Maximization the Problem Is to Compute the flight Inputs to a Hang Glider So As to Provide a Maximum Range flight
Hang Glider: Range Maximization The problem is to compute the flight inputs to a hang glider so as to provide a maximum range flight. This problem first appears in [1]. The hang glider has weight W (glider plus pilot), a lift force L acting perpendicular to its velocity vr relative to the air, and a drag force D acting in a direction opposite to vr. Denote by x the horizontal position of the glider, by vx the horizontal component of the absolute velocity, by y the vertical position, and by vy the vertical component of absolute velocity. The airmass is not static: there is a thermal just 250 meters ahead. The profile of the thermal is given by the following upward wind velocity: 2 2 − x −2.5 x u (x) = u e ( R ) 1 − − 2.5 . a m R We take R = 100 m and um = 2.5 m/s. Note, MKS units are used through- out. The upwind profile is shown in Figure 1. Letting η denote the angle between vr and the horizontal plane, we have the following equations of motion: 1 x˙ = vx, v˙x = m (−L sin η − D cos η), 1 y˙ = vy, v˙y = m (L cos η − D sin η − W ) with q vy − ua(x) 2 2 η = arctan , vr = vx + (vy − ua(x)) , vx 1 1 L = c ρSv2,D = c (c )ρSv2,W = mg. 2 L r 2 D L r The glider is controlled by the lift coefficient cL. The drag coefficient is assumed to depend on the lift coefficient as 2 cD(cL) = c0 + kcL where c0 = 0.034 and k = 0.069662. -

Mid-Atlantic Coastal and Ocean Recreation Study
New Jersey MID-ATLANTIC COASTAL AND OCEAN RECREATION STUDY The Surfrider Foundation, in partnership with Point 97, The Nature Conservancy, and Monmouth University’s Urban Coast Institute, (the Team), and in collaboration with the Mid-Atlantic Regional Council on the Ocean (MARCO), conducted a Coastal and Ocean Recreation Study (Study) for the Mid-Atlantic region in 2013-2014. The Study engaged recreational users and the public in providing data on “non-consumptive” recreational use, including surfing, diving, kayaking, beach going, and wildlife viewing. This data was previously unavailable and fills a key gap in our understanding of coastal and ocean uses in New Jersey and the Mid-Atlantic. METHODS The Team used a web-based survey accessible by mobile phones, tablets, or desktop/laptop computers to collect data from respondents on recreational use patterns, trip expenditures, and demographics. To obtain this data, the survey included a series of questions and an easy-to-use interactive mapping tool, where respondents could mark the places they went to recreate over the last year. The Team then analyzed the resulting spatial data to develop maps indicating intensity of use for recreational activities in the region (see map insert). To promote participation in the Study, the Team conducted outreach to over 300 recreational groups and businesses throughout the Mid- Atlantic region. In total, Mid-Atlantic respondents completed nearly 1,500 surveys resulting in over 22,000 unique data points. NEW JERSEY: STUDY FINDINGS Coastal and ocean recreation encompasses a popular and diverse group of activities in New Jersey (see graphic below) resulting in major economic and social benefits to coastal communities. -

TOTAL ENERGY COMPENSATION in PRACTICE by Rudolph Brozel ILEC Gmbh Bayreuth, Germany, September 1985 Edited by Thomas Knauff, & Dave Nadler April, 2002
TOTAL ENERGY COMPENSATION IN PRACTICE by Rudolph Brozel ILEC GmbH Bayreuth, Germany, September 1985 Edited by Thomas Knauff, & Dave Nadler April, 2002 This article is copyright protected © ILEC GmbH, all rights reserved. Reproduction with the approval of ILEC GmbH only. FORWARD Rudolf Brozel and Juergen Schindler founded ILEC in 1981. Rudolf Brozel was the original designer of ILEC variometer systems and total energy probes. Sadly, Rudolph Brozel passed away in 1998. ILEC instruments and probes are the result of extensive testing over many years. More than 6,000 pilots around the world now use ILEC total energy probes. ILEC variometers are the variometer of choice of many pilots, for both competition and club use. Current ILEC variometers include the SC7 basic variometer, the SB9 backup variometer, and the SN10 flight computer. INTRODUCTION The following article is a summary of conclusions drawn from theoretical work over several years, including wind tunnel experiments and in-flight measurements. This research helps to explain the differences between the real response of a total energy variometer and what a soaring pilot would prefer, or the ideal behaviour. This article will help glider pilots better understand the response of the variometer, and also aid in improving an existing system. You will understand the semi-technical information better after you read the following article the second or third time. THE INFLUENCE OF ACCELERATION ON THE SINK RATE OF A SAILPLANE AND ON THE INDICATION OF THE VARIOMETER. Astute pilots may have noticed when they perform a normal pull-up manoeuvre, as they might to enter a thermal; the TE (total energy) variometer first indicates a down reading, whereas the non-compensated variometer would rapidly go to the positive stop. -
