The invention claimed is: 1. Force-controlled throttle for adjusting the engine thrust of a combat aircraft, comprising: a handle for operation by a pilot; and a signal generating device connected to the handle for generating a control signal used for adjusting the engine torque, wherein the signal generating device is provided for generating the control signal as a function of the force exerted on the handle by the pilot in operation, wherein the signal generating device contains an elastic actuator element which is resilient against the force exerted by the pilot, contains a signal generator connected to the actuator element for generating the control signal, so that it represents the force exerted on the handle by the pilot, and contains an actuator signal generating device whose signal is connected to the signal generator for generating from the control signal an actuator signal representing the absolute value of the engine thrust to be set, and wherein the actuator element is arranged according to a force exerted by the pilot so that it is movable over a predetermined actuator displacement, and is pivotably or displaceably mounted and is connected to a spring device which generates a counterforce acting against the movement over the predetermined actuator displacement. 2. Force-controlled throttle as claimed in claim 1, wherein the actuator element is arranged according to a force exerted by the pilot so that it is movable starting from a force-free basic position in a first direction or in a second direction opposite the first direction, whereby the signal generator is provided for generating control signals in the sense of an increase in the engine thrust when there is a movement in the first direction and for generating control signals in the sense of a reduction in the engine thrust when there is a movement in the second direction. 3. Force-controlled throttle as claimed in claim 2, wherein the actuator element is movable in the first direction between the basic position and a first stop which corresponds to a maximum force in the first direction and in the second direction between the basic position and the second stop which corresponds to a maximum force in the second direction, whereby the signal generator generates control signals corresponding to an increase in engine thrust when there is a movement of the actuator element in the first direction and generates control signals corresponding to a reduction in engine thrust when there is a movement of the actuator element in the second direction. 4. Force-controlled throttle as claimed in claim 3, wherein a first defined position is provided in the actuator displacement of the actuator element in the first direction between the basic position and the first stop such that beyond this first defined position the actuator displacement in the first direction can be increased only with a definite discontinuous increase in the force exerted by the pilot, and when there is an increase in the actuator displacement beyond the defined position when the afterburner is turned off, the signal generator generates a control signal that corresponds to turning on the afterburner. 5. Force-controlled throttle as claimed in claim 4, wherein a movement of the actuator element in the first direction between the basic position and the first defined position when the afterburner is turned off corresponds to an increase in the engine thrust up to the maximum thrust without afterburner. 6. Force-controlled throttle as claimed in claim 4, wherein a movement of the actuator element in the first direction between a basic position and the first defined position with the afterburner turned on corresponds to an increase in the engine thrust up to the maximum thrust with afterburner. 7. Force-controlled throttle as claimed in claim 3, wherein a second defined position is provided in the actuator displacement of the actuator element in the second direction between the basic position and the second stop, such that beyond this second defined position, the actuator displacement of the actuator displacement of the actuator element in the second direction can be increased only with a definite discontinuous increase in the force exerted by the pilot, whereby in the case of an increase in the actuator displacement beyond the second defined position, the signal generator generates a control signal corresponding to shutdown of the afterburner in the case when the afterburner is already on. 8. Force-controlled throttle as claimed in claim 7, wherein the movement of the actuator element in the second direction between the basic position and the second defined position with the afterburner turned off corresponds to a reduction in the engine thrust down to idling. 9. Force-controlled throttle as claimed in claim 7, wherein a movement of the actuator element in the second direction between the basic position and the second defined position with the afterburner turned on corresponds to a reduction in the engine thrust down to minimal thrust with afterburner. 10. Force-controlled throttle as claimed in claim 1, wherein the signal generator generates a control signal that changes steadily with the size of the actuator displacement. 11. Force-controlled throttle as claimed in claim 1, wherein the actuator element is formed by a lever arm of a lever which is mounted to rotate about an axis of rotation, its end supporting the handle operating by the pilot. 12. Force-controlled throttle as claimed in claim 11, wherein the lever is a two-way lever mounted so that it can rotate about an axis of rotation provided in a central area, its one lever arm supporting the handle to be operated by the pilot and its other lever arm forming the actuator element. 13. Force-controlled throttle as claimed in claim 1, wherein the spring device is formed by spring elements that are linked to the actuator element and are active in the direction of movement of the actuator element. 14. Force-controlled throttle as claimed in claim 13, wherein the spring elements are arranged in pairs opposite one another on both sides of the actuator element in the direction of movement of the actuator element. 15. Force-controlled throttle as claimed in claim 14, wherein a first pair of spring elements and a second pair of spring elements are provided, arranged in pairs opposite one another in the direction of movement of the actuator element on both sides of the actuator element, the first pair of spring elements creating a counterforce which increases steadily between the basic position and the first and/or second stops of the actuator element acting against the force exerted by the pilot on the handle, and the second pair of spring elements produces an additional counterforce on exceeding the first and/or second defined position. 16. Force-controlled throttle as claimed in claim 15, wherein the first pair of spring elements is situated farther away from the axis of rotation and the second pair of spring elements is situated closer to the axis of rotation. 17. Force-controlled throttle as claimed in claim 13, wherein each spring element comprises a spiral spring, a plunger connected between the spiral spring and the actuator element and comprises a pressure plate that is displaceable by means of a threaded pin in the sense of a change in the spring bias. 18. Force-controlled throttle as claimed in claim 13, wherein the spring elements and the signal generator are situated in a housing box on which the lever carrying the actuator element and the handle is rotatably mounted. 19. Force-controlled throttle as claimed in claim 18, wherein the housing box is bordered by two opposing housing plates which are arranged in opposition to one another laterally from the actuator element and by housing plates extending parallel to the direction of movement of the actuator element, with the spring elements and the signal generator mounted on them. 20. Force-controlled throttle as claimed in claim 1, wherein the spring device creates a spring bias measured as the breakaway force required to move the actuator element out of the basic position. 21. Force-controlled throttle as claimed in claim 1, wherein the signal generator is formed by a linear potentiometer. 22. Force-controlled throttle as claimed in claim 21, wherein the linear potentiometer is connected by an operating pin to the actuator element. 23. Force-controlled throttle as claimed in claim 1, wherein the signal generating device is formed on one of an onboard computer of the vehicle and by a separate electronic circuit.
