Book excerpt: Abnormal landing scenarios of the X-38 prototype Crew Rescue Vehicle (CRV) were modeled for three different cases involving non-deployment of landing gear with an explicit dynamic nonlinear finite element code, MSC/DYTRAN. The goal of this research was to develop models to predict the probability of crew injuries. The initial velocity conditions for the X-38 with chute deployed were 10 ft/s vertical and 57 ft/s longitudinal velocity. An MSC/NASTRAN structural model was supplied by JSC and was converted to a dynamic MSC/DYTRAN model. The MSC/NASTRAN model did not include seats or floor structure; thus, the acceleration of a lumped-mass attached to the bulkhead near each assumed occupant location was used to determine injury risk for each occupant. The worst case for injury was nondeployment of all gears. The mildest case was nondeployment of one main gear. Although a probability for minor injury was predicted for all cases, it is expected that the addition of energy-absorbing floor structure and seats would greatly diminish the probability of injury.Fasanella, Edwin L. and Lyle, Karen H. and Pritchard, Jocelyn I. and Stockwell, Alan E.Langley Research CenterCOMPUTERIZED SIMULATION; FLIGHT SIMULATION; X-38 CREW RETURN VEHICLE; RESCUE OPERATIONS; LANDING GEAR; FAILURE; DYNAMIC MODELS; NONLINEARITY; FINITE ELEMENT METHOD; NASTRAN; STRUCTURAL ANALYSIS; INJURIES; RISK; PREDICTIONS

This book was released on 2018-06-13 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA incorporates skid-equipped landing gear on its series of X-38 flight test vehicles. The X-38 test program is the proving ground for the Crew Return Vehicle (CRV) a gliding parafoil-equipped vehicle designed to land at relatively low speeds. The skid-equipped landing gear is designed to attenuate the vertical landing energy of the vehicle at touchdown using crushable materials within the struts themselves. The vehicle then slides out as the vehicle horizontal energy is dissipated through the skids. A series of tests was conducted at Edwards Airforce Base (EAFB) in an attempt to quantify the drag force produced while "dragging" various X-38 landing gear skids across lakebed regions of varying surface properties. These data were then used to calculate coefficients of friction for each condition. Coefficient of friction information is critical for landing analyses as well as for landing gear load and interface load analysis. The skid specimens included full- and sub-scale V201 (space test vehicle) nose and main gear designs, a V131/V 132 (atmospheric flight test vehicles) main gear skid (actual flight hardware), and a newly modified, full-scale V201 nose -ear skid with substantially increased edge curvature as compared to its original design. Results of the testing are discussed along with comments on the relative importance of various parameters that influence skid stability and other dynamic behavior.

Download or read book Microsoft Flight Simulator X For Pilots written by Jeff Van West and published by John Wiley & Sons. This book was released on 2012-02-15 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Get ready to take flight as two certified flight instructors guide you through the pilot ratings as it is done in the real world, starting with Sport Pilot training, then Private Pilot, followed by the Instrument Rating, Commercial Pilot, and Air Transport Pilot. They cover the skills of flight, how to master Flight Simulator, and how to use the software as a learning tool towards your pilot’s license. More advanced topics demonstrate how Flight Simulator X can be used as a continuing learning tool and how to simulate real-world emergencies.

Available in PDF, EPUB and Kindle. Book excerpt: On of the problems facing the aircraft community is landing gear dynamics, especially shimmy and brake-induced vibration. Shimmy and brake-induced vibrations can lead to accidents due to excessive wear and shortened life of gear parts and contribute to pilot and passenger discomfort. To increase understanding of these problems, a literature survey was performed. The major focus is on work from the last ten years. Some older publications are included to understand the longevity of the problem and the background from earlier researchers. The literature survey includes analyses, testing, modeling, and simulation of aircraft landing gear; and experimental validation and characterization of shimmy and brake-induced vibration of aircraft landing gear. The paper presents an overview of the problem, background information, and a history of landing gear dynamics problems and solutions. Based on the survey an assessment and recommendations of the most critically needed enhancements to the state of the art will be presented. The status of Langley work contributing to this activity will be given.
