专利汇可以提供Method and apparatus for detecting stall buffet专利检索，专利查询，专利分析的服务。并且An aircraft instrument has been designed to indicate impending stall buffet. An angle of attack indicator is provided with a dial having two scales, one displaying angles of attack and the other displaying the maximum Mach number that may be flown for each angle of attack. A Mach number indicator is associated with the Mach scale to display the aircraft''s operating Mach number. Stall buffet is indicated when the values of the maximum Mach number and the operating Mach number converge on one another. Additionally, the present instrument will also indicate the maximum angle of attack that can be flown for each operating Mach number. Stall buffet will be indicated when the values of the operating and maximum angle of attack converge. Separate warning means and aircraft control actuators can be provided so as to indicate impending stall buffet and to control the aircraft so as to remove it from approaching stall buffet.，下面是Method and apparatus for detecting stall buffet专利的具体信息内容。

权利要求

1. An aircraft instrument for indicating impending stall buffet, said instrument including: a. an angle of attack indicator with a scale calibrated in degrees of angle of attack and with a pointer associated with said angle of attack scale so as to display the plane''s angle of attack; b. a Mach number scale adjacent and related to the angle of attack scale so as to represent for the corresponding angle of attack the Mach number at which stall buffeting will begin; and c. a Mach meter pointer associated with said Mach number scale to display the value of the Mach number of the aircraft thereon.

2. The aircraft instrument of claim 1 further including: d. a control circuit to sense the difference between the Mach number at which stall buffeting will be initiated and the aircraft''s operating Mach number and to generate a control signal proportional to the difference between the two Mach numbers; and e. a warning indicator responsive to the control signal.

3. The aircraft instrument as claimed in claim 2 wherein the warning indicator is calibrated to visually display the difference between the aircraft''s operating Mach number and the Mach number at which stall buffeting will begin.

4. Apparatus for indicating impending stall buffet comprising: a. A dial with one scale calibrated in degrees of angle of attack and a second scale adjacent to the first scale calibrated so as to display the maximum Mach number for that attack before which stall buffeting is initiated; b. an angle of attack indicator in conjunction with the said dial whereby both the angle of attack and the corresponding maximum Mach number for that angle of attack are displayed; and c. a Mach number indicator arranged in conjunction with said dial so as to display both the Mach number at which the aircraft is operating and the corresponding maximum angle of attack for that Mach number.

5. Apparatus of claim 4 further including: d. control circuit to sense the difference between the maximum and operating Mach number and to generate a signal proportional to this difference; and e. warning means responsive to the said generated signal to display this difference.

6. An aircraft instrument for indicating impending stall buffet, said instrument including: a. Mach meter with a scale calibrated in Mach numbers and with a pointer associated with said Mach number scale so as to display the aircraft''s operating Mach number; b. An angle of attack scale adjacent and related to the Mach number scale so as to represent opposite the aircraft''s operating the corresponding angle of attack at which stall buffeting will occur; and c. a angle of attack indicator associated with said angle of attack scale to display the value of the angle of attack at which the aircraft is operating.

7. The aircraft instrument of claim 6 further including: d. a control circuit to sense the difference between the angle of attack at which stall buffet will occur and the aircraft''s operating angle of attack and to generate a control signal that is proportional to the difference between the two angles of attack; and e. a warning indicator responsive to the signal generated by the control circuit.

8. The aircraft instrument of claim 7 wherein the warning indicator visually displays the difference between the aircraft''s operating angle of attack and the angle of attack at which stall buffeting occurs.
