The performance analysis of the supersonic pulse-detonation-jet engine system represents some revision of earlier results, including new ideas of scavenging flow. Curves of the drag coefficient of a typical supersonic long- range missile showed that four 36-in.-diam engines have enough reserve power to propel the missile through sonic flight velocities and up to a flight Mach number of 2.80. A unit small enough to be mounted on the blade tip of a helicopter was analyzed. The unit has a maximum...

An engine capable of propelling a guided missile from zero flight speed to a cruising Mach number of 2.80 was assumed. The detonation tubes are arranged in 6 concentric rows of 32 tubes each, which gives an engine diameter of 34 in. The length of the tubes is 15 in., and the over-all length of the engine is 55 in. The engine dry weight is about 900 lb. The shock wave produced during the pulse compression phase will be used to ignite or detonate the fuel- air mixture. The most suitable structure...

The quantity which is considered most important is the build-up factor for a monoenergetic, monoangular beam of photons incident on a slab of finite thickness but infinite extent. This quantity is obtained for a set of discrete values of slab thickness, in mean free paths, over the interval (o,20); incident energy, in units of mc squared, over the interval (1,20); and incident angle, in degrees, over the interval (0,90). Pb and Fe are used for the slab. The processes used to obtain the set of...

The engine consists of a large number of tiny pulsejet tubes assembled into a matrix. It differs from the standard pulsejet in that it achieves a shock compression prior to combustion and in addition completes the combustion at constant volume. A typical tube is about 0.25 to 0.5 in. in diam and 6 in. long. A jet unit producing a thrust of 150 lb at a maximum temperature of 3000 deg F would have an 8.25-in. diam, a weight of 43 lb, and a specific fuel consumption of 1.86 lb/hr/lb of thrust. A...

$EVERAL TOPICS RELATING TO THE REDUCTION OF DRAG DUE TO LIFT AT SUPERSONIC SPEEDS ARE DISCUSSED. The distribution of camber for optimial loading of diamond planform wings and some low drag geometries for rectangular wings are determined. It appears that substantial drag reduction, through the use of spanwise distribution of camber, may be achieved only for low reduced aspect ratios, M2-1 AR. The distribution of lift throughout volumes of prescribed shape is considered and some optimum...

In a previous report a statistical theory of radar detection was presented in outline form. The mathematical details were omitted. In order that the main ideas and results might be made available as soon as possible. This report contains the mathematics that led to the results presented in Ref. 28. In addition, several subjects are briefly discussed that were not covered in Ref. 28. These are collapsing loss, antenna beam shape loss, the effect of signal injection, limiting loss, and moving...

The determination of optimum solutions to systems of linear inequalities has assumed increasing importance as a tool for mathematical analysis of certain problems in economics, logistics, and the theory of games. This paper develops a theory for avoiding assumptions regarding rank of underlying matrices which has import in applications where little or nothing is known about the rank of some linear inequality system requiring solution.

A unimodel function of one variable is defined on an interval. No regularity conditions involving continuity, derivatives, etc., are assumed. We wish to minimize the number of calculations of values of the function in order to assure the location of its maximum to a prescribed degree of accuracy. The solution of this problem and its discrete analogue involves the well-known Fibonacci sequence.
