Book Description
The report describes the results of an experimental study concerning the injection of a gaseous secondary jet into an unbounded supersonic flow field which was uniform outside of a turbulent boundary layer. The investigation was principally concerned with the definition of the proper scale length to be associated with turbulent two-dimensional jet-interaction flows. In support of this objective, results are presented for a Mach 4 test conducted using a flat-plate model containing a sonic secondary jet directed normal to the mainstream. Secondary jet strengths were varied from approximately 0 to 1000 for jet throat sizes of 0.005 inch, 0.020 inch and 0.030 inch. The jet interaction phenomenon was studied using detailed surface pressure distributions measured fore and aft of the secondary jet in conjunction with comprehensive shadowgraph coverage of the interaction flow field.

Book Description
An experimental study of the control forces and moments generated by a slot-type secondary jet located near the base of an ogive cylinder in a Mach 4 and 5 free stream was conducted in the NOL Supersonic Tunnel No. 2. The free-stream Reynolds number, based on body length, was held constant at 22,000,000 and the missile angle of attack was varied from -10 to +10 degrees. The jet slot spanned one quadrant of the cylindrical surface and was contained between two low aspect ratio fins. (Author).

Correlation Parameters for Two-dimensional Jet Interaction

ISBN:
Category : Boundary layer
Languages : en
Pages : 62
Book Description
The problem considered is the separation of the boundary layer on a flat plate in a high supersonic free stream caused by the normal injection of a two-dimensional sonic or supersonic jet. Only the separation region forward of the jet is discussed. Data from existing literature has been analyzed to form dimensionless correlation parameters that will accurately predict the force, center-of-pressure, and separation length that characterize this forward separation region. Problems related to the nozzle discharge coefficient are discussed. The functional relations of these correlations with respect to changes in jet stagnation temperature and pressure, nozzle throat width, and Mach number for fixed free stream conditions are also discussed.

Book Description
This report summarizes the methods available to predict the aerodynamic static, dynamic, and control characteristics of missiles. The methods selected for Missile Datcom development were based upon a criteria which included ease of use, accuracy, utility over a range of flight conditions and cost effective in their use. This report describes the methodology appropriate for the missile designer. An outline of a Missile Datcom handbook is proposed; an automated version is also recommended for development. Those areas presently lacking suitable methodologies are also highlighted. (Author).
