Book Description
A theoretical analysis, based on the linearized equation for supersonic flow, of characteristics of triangular-tip control surfaces on thin triangular wings. By restriction to case for which Mach lines from wing apex lie behind the leading edge, a simplified treatment was possible; results of previous work on lift of triangular wings could be used to derive expressions for lift effectiveness, pitching moment, rolling-moment effectiveness, hinge moment due to control deflection, and hinge moment due to angle of attack. Comparisons were made with two-dimensional case.

Characteristics of Thin Triangular Wings with Constant-chord Full-span Control Surfaces at Supersonic Speeds
Author: Warren A. Tucker
Publisher:
ISBN:
Category : Aerodynamics, Supersonic
Languages : en
Pages : 25
Book Description
A theoretical analysis was made of the characteristics of constant-chord, full-span control surfaces on thin triangular wings at supersonic speeds by use of methods based on the linearized equation for supersonic flow. Expressions were found for lift effectiveness, pitching-moment coefficient, hinge-moment coefficient due to control deflection, and hinge-moment coefficient due to angle of attack. These expressions were given as functions of the ratio of flap chord to wing chord and the ratio of the tangent of the wing-semiapex angle to the tangent of the Mach angle.

Characteristics of Thin Triangular Wings with Constant-chord Partial-span Control Surfaces at Supersonic Speeds
Author: Warren A. Tucker
Publisher:
ISBN:
Category : Aerodynamics, Supersonic
Languages : en
Pages : 43
Book Description
A theoretical analysis was made of characteristics of constant-chord partial-span control surfaces on thin triangular wings at supersonic speeds by use in methods based on linearized theory for supersonic flow. Two cases were treated: In one the flap extended outboard from the center of wing and in the other the flap extended inboard from wing tip. Expressions were found for lift coefficient, rolling-moment coefficient, and hinge-moment coefficient due to flap deflection, hinge-moment coefficient due to angle of attack, and pitching-moment coefficient due to flap lift. A few figures are given to illustrate application equations.

Electrical Techniques for Compensation of Thermal Time Lag of Thermocouples and Resistance Thermometer Elements
Author: Charles E. Shepard
Publisher:
ISBN:
Category : Amplifiers (Electronics)
Languages : en
Pages : 740
Book Description
Basic electrical networks are described that compensate for the thermal time lag of thermocouple and resistance thermometer elements. For a given set of operating conditions, networks requiring no amplifiers can provide a thirtyfold reduction in effective time lag. This improvement is obtained without attenuation of the voltage signal, but does result in a large reduction in the amount of electric power available because of an increase in the output impedance of the network. Networks used commercially available amplifiers can provide a thousandfold reduction in the effective time lag without attenuation of the alternating voltage signal or or the available electric power, but the improvement is often obtained at the expense of loss of the zero-frequency signal. The completeness of compensation is limited by the extent of off-design operation required.
