Prospects for obtaining aerodynamic heating results from analysis of meteor flight data by H. Julian Allen( Book )

Pressure distribution and some effects of viscosity on slender inclined bodies of revolution by H. Julian Allen( Book )

5 editions published in 1950 in English and held by 14 WorldCat member libraries worldwide

The simplified solution for the pressure distribution of slender inclined bodies of revolution is developed. The solution should be suitable for bodies of high fineness ratio even at low supersonic speeds, provided the angle of attack is small. Comparison with low-speed experimental results indicates that the observed flow separation phenomena can be explained in terms of the calculated pressure distributions together with the theory of oblique viscous flows

A comparative analysis of the performance of long-range hypervelocity vehicles by A. J Eggers( )

2 editions published in 1957 in English and held by 9 WorldCat member libraries worldwide

Long-range hypervelocity vehicles are studied in terms of their motion in powered flight, and their motion and aerodynamic heating in unpowered flight. Powered flight is analyzed for an idealized propulsion system which rather closely approaches present-day rocket motors. Unpowered flight is characterized by a return to earth along a ballistic, skip, or glide trajectory. Only those trajectories are treated which yield the maximum range for a given velocity at the end of powered flight. Aerodynamic heating is treated in a manner similar to that employed previously by the senior authors is studying ballistic missiles (NACA RM A53D28), with the exception that radiant as well as convective heat transfer is considered in connection with glide and skip vehicles
A study of effects of viscosity on flow over slender inclined bodies of revolution by H. Julian Allen( Book )

The Effect of compressibility on the growth of the laminar boundary layer on low-drag wings and bodies by H. Julian Allen( Book )

2 editions published in 1947 in English and held by 7 WorldCat member libraries worldwide

The development of the laminar boundary layer in a compressible fluid is considered. Formulas are given for determining the boundary-layer thickness and the boundary-layer Reynolds number, which is a measure of the boundary-layer stability, for airfoils and bodies of revolution

A study of the motion and aerodynamic heating of ballistic missiles entering the earth's atmosphere at high supersonic speeds by H. Julian Allen( Book )

Wall interference in a two-dimensional-flow wind tunnel with consideration of the effect of compressibility by H. Julian Allen( Book )

5 editions published in 1944 in English and held by 6 WorldCat member libraries worldwide

Theoretical tunnel-wall corrections are derived for an airfoil of finite thickness and camber in a two-dimensional-flow wind-tunnel. The theory takes account of the effects of the wake of the airfoil and of the compressibility of the fluid, and is based upon the assumption that the chord of the airfoil is small in comparison with the height of the tunnel. Consideration is given to the phenomenon of choking at high speeds and its relation to tunnel-wall corrections. The theoretical results are compared with the small amount of low-speed experimental data available and the agreement is seen to be satisfactory, even for relatively large values of the chord-height ratio
A Simplified method for the calculation of airfoil pressure distribution by H. Julian Allen( Book )

3 editions published in 1939 in English and held by 6 WorldCat member libraries worldwide

Base-profile pressure-coefficient distributions for the usual N.A.C.A. family of airfoils, which are also suitable for several other commonly employed airfoils, are included in tabular form. With these tabulated base-profile pressures and the computed normal-force distributions, pressure distributions adequate for most engineering purposes can be obtained
A method for calculating heat transfer in the laminar flow region of bodies by H. Julian Allen( Book )

3 editions published between 1942 and 1943 in English and held by 6 WorldCat member libraries worldwide

This report has been prepared to provide a practical method for determining the chordwise distribution of the rate of heat transfer from the surface of a wing or body of revolution to air. The method is limited in use to the determination of heat transfer from the forward section of such bodies when the flow is laminar. A comparison of the calculated average heat-transfer coefficient for the nose section of the wing of a Lockheed 12-A airplane with that experimentally determined shows a satisfactory agreement. A sample calculation is appended
Calculation of the chordwise load distribution over airfoil sections with plain, split, or serially hinged trailing-edge flaps by H. Julian Allen( Book )

Dynamic stability of vehicles traversing ascending or descending paths through the atmosphere by Murray Tobak( Book )

3 editions published in 1958 in English and held by 5 WorldCat member libraries worldwide

An analysis is given of the oscillatory motions of vehicles which traverse ascending and descending paths through the atmosphere at high speed. The specific case of a skip path is examined in detail, and this leads to a form of solution for the oscillatory motion which should recur over any trajectory. The distinguishing feature of this form is the appearance of the Bessel rather than the trigonometric function as the characteristic mode of oscillation
The asymmetric adjustable supersonic nozzle for wind-tunnel application by H. Julian Allen( Book )

3 editions published between 1948 and 1953 in English and held by 5 WorldCat member libraries worldwide

The advantages and disadvantages of this nozzle relative to the conventional interchangeable-fixed-block and flexible-wall nozzles are discussed
A study of the motion and aerodynamic heating of missiles entering the earth's atmosphere at high supersonic speeds by H. Julian Allen( Book )

2 editions published in 1957 in English and held by 5 WorldCat member libraries worldwide

A simplified analysis of the velocity and deceleration history of missiles entering the earth's atmosphere at high supersonic speeds is presented. The results of this motion analysis are employed to indicate means available to the designer for minimizing aerodynamic heating. The heating problem considered involves not only the total heat transferred to a missile by convection, but also the maximum average and local time rates of convective heat transfer
The problem of longitudinal stability and control at high speeds by Manley J Hood( Book )

2 editions published in 1943 in English and held by 4 WorldCat member libraries worldwide

The difficulty in pulling out of high-speed dives, experienced with some airplanes, is show to be due, to the wing, to the effect of compressibility on the lift of the wing. As the Mach number is increased above the critical for the wing, there is a marked decrease in the lift-curve slope in the downwash at the tail plane, and also a shift in the angle of attack for zero lift. These changes bring about an increase in the static longitudinal stability and alter the trim. Frequently the change in trim is such as to promote a diving tendency which, because of the increased stability, cannot be overcome by use of the normal elevator control
Motion of a ballistic missile angularly misaligned with the flight path upon entering the atmosphere and its effect upon aerodynamic heating, aerodynamic loads, and miss distance by H. Julian Allen( Book )

1 edition published in 1957 in English and held by 3 WorldCat member libraries worldwide

An analysis is given of the oscillating motion of a ballistic missile which upon entering the atmosphere is angularly misaligned with respect to the flight path. The history of the motion for some example missiles is discussed from the point of view of the effect of the motion on the aerodynamic heating and loading. The miss distance at the target due to misalignment and to small accidental trim angles is treated. The stability problem is also discussed for the case where the missile is tumbling prior to atmospheric entry
