Spoilers, split flaps and sometimes (with thin aerofoils) incidence alone cause the flow to separate from the aerofoil surface. This flow often reattaches to form a closed bubble of virtually stationary air at a fairly ...
Summary. Experiment has already shown that the aerodynamic damping on half-span models in pitching oscillation is subject to interference effects that may exceed 30 per cent in slotted-wall tunnels at subsonic speeds. An ...
Summary. This Report gives a description of an extension to wings oscillating at general frequencies of Multhopp\\'s lifting-surface theory for wings in steady subsonic flow. This particular variant of the \\'kernel ...
The basis for designing parachutes of R. & M. 862 did not appear to be correct for parachutes with cords over the canopy. Moreover, the presence of these cords was essential in a practical design for heavy duty purposes ...
The Report presents a theory of the aerodynamic interference between a helicopter rotor blade and a fuselage or wing. A two-dimensional analysis is made to which a correction factor is applied to convert the two-dimensional ...
A theory of blockage constraint on the flow past a bluff body in a closed wind tunnel is developed, using an approximate relation describing the momentum balance in the flow outside the wake, and two empirical auxiliary relations.
The simple model used by Brown and Michael to represent the flow past a slender delta wing with leading edge separation, is extended to treat wings which have pointed apexes, curved leading edges and straight, unswept ...
The,torsional vibrations of a four-boom cylinder of doubiy symmetrical rectangular cross-section are considered and the differential equation of motion is derived on the assumption that the ribs maintain the section shape ...
The post-buckling behaviour of a circular plate is investigated for two conditions--heating over the centre and heating at the edge. In the former case the plate buckles into the form of a saucer; in the latter into a ...
A continuous solution is derived for the stress distribution in a simple wing surface represented by a uniformly reinforced stri p bounded by equal constant area edge members, when the sections in the airstream experience ...
Thermodynamic charts giving enthalpy, entropy, temperature, pressure and specific volume, have been constructed for the products of combustion of a hydrocarbon fuel (85 per cent C, 15 per cent H by weight) with nitric acid ...
Thermodynamic charts showing enthalpy, entropy and specific volume for a range of pressures and temperatures have been constructed for the decomposition products of 80, 85 and 90 per cent w/w hydrogen peroxide (H.T.P.) for ...
The essential features of a practical method of determining gas turbine performance are that it shall be suitable for accurate routine calculation, and that it is capable of simple modification in order to deal with a range ...
