This book was released on 2018-06 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of an inviscid computational study conducted on two aeroshell configurations for a proposed '07 Mars Lander. The aeroshell configurations are asymmetric due to the presence of the tabs at the maximum diameter location. The purpose of these tabs was to change the pitching moment characteristics so that the aeroshell will trim at a non-zero angle of attack and produce a lift-to-drag ratio of approximately -0.25. This is required in the guidance of the vehicle on its trajectory. One of the two configurations is called the shelf and the other is called the tab. The unstructured grid software FELISA with the equilibrium Mars gas option was used for these computations. The computations were done for six points on a preliminary trajectory of the '07 Mars Lander at nominal Mach numbers of 2, 3, 5, 10, 15, and 24. Longitudinal aerodynamic characteristics namely lift, drag, and pitching moment were computed for 10, 15, and 20 degrees angles of attack. The results indicated that the two configurations have aerodynamic characteristics that have very similar aerodynamic characteristics, and provide the desired trim LID of approximately -0.25.Prabhu, Ramadas K.Langley Research CenterCOMPUTATIONAL FLUID DYNAMICS; INVISCID FLOW; AEROSHELLS; SPACECRAFT STRUCTURES; MACH NUMBER; TABS (CONTROL SURFACES); ASYMMETRY; UNSTRUCTURED GRIDS (MATHEMATICS); AERODYNAMIC CHARACTERISTICS; LIFT DRAG RATIO; HYPERSONIC SPEED; AERODYNAMIC LOADS

This book was released on 2018-08-27 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of a study conducted to compute the inviscid longitudinal aerodynamic characteristics of three aeroshell configurations of the proposed '07 Mars lander. This was done in support of the activity to design a smart lander for the proposed '07 Mars mission. In addition to the three configurations with tabs designated as the shelf, the canted, and the Ames, the baseline configuration (without tab) was also studied. The unstructured grid inviscid CFD software FELISA was used, and the longitudinal aerodynamic characteristics of the four configurations were computed for Mach number of 2.3, 2.7, 3.5, and 4.5, and for an angle of attack range of -4 to 20 degrees. Wind tunnel tests had been conducted on scale models of these four configurations in the Unitary Plan Wind Tunnel, NASA Langley Research Center. Present computational results are compared with the data from these tests. Some differences are noticed between the two results, particularly at the lower Mach numbers. These differences are attributed to the pressures acting on the aft body. Most of the present computations were done on the forebody only. Additional computations were done on the full body (forebody and afterbody) for the baseline and the Shelf configurations. Results of some computations done (to simulate flight conditions) with the Mars gas option and with an effective gamma are also included.Prabhu, Ramadas K. and Sutton, Kenneth (Technical Monitor)Langley Research CenterAERODYNAMIC CHARACTERISTICS; AEROSHELLS; COMPUTATIONAL FLUID DYNAMICS; INVISCID FLOW; MACH NUMBER; MARS MISSIONS; WIND TUNNEL TESTS; FLIGHT CONDITIONS; SCALE MODELS; ANGLE OF ATTACK; SUPERSONIC SPEED; AFTERBODIES...
