Stability
One definition of stability in regard to aircraft is:
The quality of an aircraft in flight which causes it to return to a condition of equilibrium when meeting a disturbance.[1]
There were efforts to make aircraft more stable in the air, and so this is a technological category for patents and publications.
Lawrence Hargrave made a useful finding that box kites were more stable than flat kites in the wind, and this led to the development of biplanes.
Some inventors focused on designing self-correcting systems, in which a tilt in one direction would predictably cause a compensatory corrective force.
Maxim, 1909, Artificial and Natural Flight, p. 92:
A ship at sea has only to be steered in a horizontal direction; the water in which it is floated assures its stability in a vertical direction; but when a flying machine is once launched in the air, it has to be steered in two directions—that is, the vertical and the horizontal. Moreover, it is constantly encountering air currents that are moving with a much higher velocity than any water currents that have ever to be encountered. It is, therefore, evident that, as far as vertical steering is concerned, it should be automatic.
(He recommends the gyroscope as the only acceptable means for accomplishing this type of stability.)
Stability versus control
Stability is closely related to the issue of how the pilot can control the aircraft (navigation or piloting), as the pilot may be able to accomplish through directed control the object of restoring the aircraft to a stable course. According to aviation historian Charles Harvard Gibbs-Smith, the European engineers of the first decade in the twentieth century were wedded to the "inherent stability" model, while the Wright Brothers had chosen to develop control systems.[2]
Crouch, 1981, p. 36, writes on the same subject:
Most experimenters chose simply to ignore the possibility of active pilot control in roll. Following the lead of French experimenter Alphonse Pénaud, they sought to perfect a mechanism that would guarantee absolute inherent lateral stability. This would mean that a flaying machine would proceed on a straight and level course, with the pilot intervening only when changing direction or altitude. Thus, a simple mechanism such as building dihedral into the wings, which would provide some measure of stability in roll, was substituted for an active control system. The rudder alone would be used to swing the aircraft around in a slow, flat turn, perhaps assisted by some device that could increase air resistance on the pivoting wing.
A number of factors explain this emphasis on automatic stability. Many students of the atmosphere were so convinced that upper-air gusts and currents shifted so rapidly as to defeat human reflexes. They believed that a mechanism that could "sense" these changes and automatically maintain the craft on an even keel was required. [...]
Just as important, however, is the fact that few experimenters really sought to develop a finished aircraft, complete with adequate controls. Most felt that the first task was to demonstrate a simple straight-line flight with a man on board. Once this had been accomplished, they argued, full attention could be given to control.
Automatic stability of the Airplane
Throughout our data we find specifically “automatic airplane stability”, achieved by way of several fairly distinct and quantifiable modalities. Though it is highly unlikely that any innovation oriented towards stability would be designed to involve undue burden on the aviator, we may want to subcategorize this further.
We have extensive publications on issues of automatic stability, on false claims thereto, on "dangers" thereof, on relations between "automatic" and other.
Patent FR-1912-455480 is a case of interest emphasizing innovations in control which are applicable whether "automatic" or "optional".
In contrast, at least semantically, Patent FR-1911-434663, along with its addition, gives us an example of stability which is not only "automatic" but "required", or "imperative".
Patent FR-1910-424474 and its addition give us an instance in which automatic airplane stability, achieved via control wind resistance, is conjointly manifest with speed regulation, or "cruise control".
Patent US-1908-927605 has the properties of automatic stability and also allows for direct adjustment by the pilot.
Distinct and fundamental principles upon which stability is based, automatically or otherwise
Over time, drawing from received patent data, we notice 3-4 semi-distinct principles through which airplane stability achieved. These all corresponding tech areas. Any perusal of pendulum or gyroscope results, for instance, will show a prevalence of stability and-or the clearly related equilibrium.
- pendulum
- gyroscope
- aerodynamics, Sam Leonard Walkden being an inventor with an emphasis on this field, and its applicability to stability and automatic stability, as reflected both in his patents and in his publications ; Walkden's Patent GB-1915-9370 takes this aerodynamics focus, tangent to incidence, and builds upon it, still focused on automatic stability, and bringing in the capacities of the gyroscope.
- wing warping
- propellers; this is rare, in terms of cross-reference with stability
- incidence
Particular cases
- Patent FR-1906-364747 achieves automatic stability via a combination of the effects of aerodynamics and the pendulum.
- Patent FR-1909-400762, of Édouard Dulière, uses the weight of the pilot in the assurance of stability.
- Patent GB-1910-6051, Sam Leonard Walkden, uses specifically wind-driven "fans" in the furtherance of automatic stability.
- The above-mentioned principles are not mutually exclusive in terms of their applicability to airplane stability. Patent FR-1910-433152 of Louis Marmonier makes use of both the pendulum and the gyroscope. It also has to do with incidence-related control of the elements of automatic stability.
- Patent FR-1910-416049 of Hector-Georges Villeneuve achieves automatic stability of the airplane via the overall aerodynamics of its design, with particular focus on its “gouvernail-équilibreur”.
- Patent FR-1910-419471 of Wilhelm Heine maintains stability and equilibrium by way of a telescopic apparatus connected via cables to various aerodynamic and other components, the tubes constituting the telescopic apparatus behaving responsively, with a pendulum also being involved.
- Patent FR-1910-423459 gives automatic stability in a manner integrated with all surfaces and apparatus of control and steering.
- Patent FR-1911-431914 features aircraft stability, and likely automatic stability, by way of aerodynamics, that is, stability achieved by way of mobile ailerons governed ultimately by a pendulum.
- Patent FR-1911-433494 takes the gyration of air currents created in the interests of propulsion, and uses this force or energy in the interests of stability and sustentation.
- Patent FR-1911-437060 of Benoît-Fortuné Martel dit Baillaud very cleanly emphasizes the pendulum, with a perfect pendulum constituting the patents sole diagram.
- Patent FR-1911-428887 is an exceedingly odd vehicle, and needs further study, also uses air currents created in the interests of propulsion, condensing this air, and maximizes its effects, towards various ends including those of stability, which would be automatic.
- Patent GB-1912-483, of William Jacob Wilson, achieves automatic stability, applicable both to HTA and LTA, via the pendulum.
- Patent FR-1912-444465 apparently has to do with using the aerodynamics of the overall fuselage design to attain automatic stability, in all of its applications, stability during flight, the avoidance of falls, and the prevention of violent landings.
- Patent FR-1912-449431 is a case in which inertia is specifically and titularly emphasized as the means employed in the interests of stability.
- Patent FR-1914-469662 of Pierre-Ambjorn Sparre features a pendulum, or even a fairly simple weight, which hangs beneath the aircraft, and thus achieves stability.
- Patent BE-1914-266877 is stability achieved by way of a vertical-axis propellers situated above the pilot, with a clear emphasis on the stability being specifically “réglable”, as opposed to “automatique”.
- The work of Attila Pédery and Desiderius Varsányi and Aladar Zoltán, descending from a purported Patent HU-1913-Pédery-Varsányi-Zoltán, and fleshed out in Patent FR-1914-469080 and Patent GB-1914-4306, consists in automatic stability activated via the buoyancy or upward thrust of a liquid. This stabilizer is positively connected to the lift and stability planes of the aircraft. This principle is treated as an advance over related attempts focused on the pendulum and the gyroscope.
- Patent GB-1916-104346 of Carl Alfred Johansson involves a frame, “pivotally mounted on the machine”, that is, distinct from the frame of or within the aircraft itself, this additional frame aiding in the furtherance of automatic stability.
