Aerodynamic Thrust Vectoring for Attitude Control of a Vertically Thrusting Jet Engine

Jet Attachment Behavior using Counterflow Thrust Vectoring

A modeling and experimental study was performed to examine the jet attachment process, which can develop during the fluidic thrust vector control of subsonic and supersonic jets. Experiments performed in rectangular jets up to Mach 1.4 revealed that continuous control of jet exhaust is possible with secondary mass flow rates of the order of 1% of the primary jet mass. Under certain operating co...

The Jet Multiplicity as a Function of Thrust

We calculate the average multiplicity of jets in ee annihilation as a function of both the jet resolution parameter, ycut, and the thrust T . Our result resums to all orders the leading and next-to-leading logarithms in ycut and 1− T , and is exact up to second order in αS. This allows a comparison between the number of jets found using jet algorithms and the ability to distinguish different je...

Some Details of Nonlinear Estimation

The traditional view adopted by statistics and econometrics texts is that, in order to solve a nonlinear least squares (NLS) or nonlinear maximum likelihood (NML) problem, a researcher need only use a computer program. This point of view maintains two implicit assumptions: (1) one program is as good as another; and (2) the output from a computer is reliable. Both of these maintained assumptions...
