X-33 Hypersonic Aerodynamic Characteristics [PDF]

open access: yesJournal of Spacecraft and Rockets, 1999
Lockheed Martin Skunk works, under a cooperative agreement with NASA, will build and fly the X-33, a half-scale prototype of a rocket-based, single-stage-to-orbit (SSTO), reusable launch vehicle (RLV). A 0.007-scale model of the X-33 604B0002G configuration was tested in four hypersonic facilities at the NASA Langley Research Center to examine vehicle ...

X-34 vehicle aerodynamic characteristics [PDF]

open access: yes16th AIAA Applied Aerodynamics Conference, 1998
The X-34, being designed and built by the Orbital Sciences Corporation, is an unmanned sub-orbital vehicle designed to be used as a flying test bed to demonstrate key vehicle and operational technologies applicable to future reusable launch vehicles. The X-34 will be air-launched from an L-1011 carrier aircraft at approximately Mach 0.7 and altitudes ...

Nonlinear Feedback Control of Axisymmetric Aerial Vehicles [PDF]

open access: yes, 2014
We investigate the use of simple aerodynamic models for the feedback control of aerial vehicles with large flight envelopes. Thrust-propelled vehicles with a body shape symmetric with respect to the thrust axis are considered.

The Aerodynamic Characteristics of Steam Turbine Reaction Stages. (Aerodynamic Characteristics of Multistages).

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991
The aerodynamic characteristics of reaction stages of a large steam turbine have been studied for the purpose of performance improvement. For the second step, the characteristics of the multistage with typical reaction bladings were studied by two-dimensional low-speed cascade tests and three-stage air turbine tests.

Aerodynamic Characteristics of Steam Turbine Reaction Stages. (Aerodynamic Characteristics of a Single Stage).

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991
The aerodynamic characteristics of reaction stages of a large steam turbine have been studied for the basis of performance improvement. For the first step, the characteristics of a single reaction stage with typical reaction blading were studied by two-dimensional low-speed cascade tests and single-stage air turbine tests.

Aerodynamic characteristics of a hypersonic parachute [PDF]

open access: yes, 1961
Newtonian theory, both in the form of the Modified-Newtonian and the Newton- Busemann pressure laws, is used to find the shape, cloth area and drag of the axisymmetric canopy of a hypersonic parachute, whose only load-carrying fibres are longitudinal ...

Aerodynamic characteristics of grain sorghum

open access: yesAgricultural and Forest Meteorology, 1986
Wind speeds were measured above grain sorghum (Sorghum bicolor L. Moench cv. DK-57) canopies at Mead, Nebraska, during the 1982 and 1983 growing seasons. The crop was planted in north-south-oriented rows 0.76 m apart. The plant population per ha was about 276 000 in 1982 and 118 500 in 1983.

Aerodynamic Characteristics of Airfoil Using Panel Method [PDF]

open access: yes, 2016
Potential flow over an airfoil plays an important historical role in the theory of flight. The governing equation for potential flow is Laplace\u27s equation, a widely studied linear partial differential equation. One of Green\u27s identities can be used

Aerodynamic Characteristics of Swept Propellers

open access: yesJournal of the Japan Society for Aeronautical and Space Sciences, 1984
The vortex lattice method is applied to calculations of the aerodynamic characteristics of propellers. A blade of the propeller is divided into many trapezoidal panels, and each panel is represented by a spiral horse shoe vortex in which a bound vortex is placed on the 1/4chord line of the panel, and a pair of wake vortices is emitted from the both ...
