Load factor (aeronautics) In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight [1][2]: § 5.22 and represents a global measure of the stress ("load") to which the structure of the aircraft is subjected: where. is the weight. Since the load factor is the ratio of two forces, it is dimensionless.
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...
A load factor is a critical statistic of a hash table, and is defined as follows: [1] =, where n {\displaystyle n} is the number of entries occupied in the hash table. m {\displaystyle m} is the number of buckets.
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. [1][2] The term is somewhat loosely applied, and can also refer to other measurements such as maneuverability.
A dynamic load can have a significantly larger effect than a static load of the same magnitude due to the structure's inability to respond quickly to the loading (by deflecting). The increase in the effect of a dynamic load is given by the dynamic amplification factor (DAF) or dynamic load factor (DLF):
Power factor. In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing work.
Utilization factor. The utilization factor or use factor is the ratio of the time that a piece of equipment is in use to the total time that it could be in use. It is often averaged over time in the definition such that the ratio becomes the amount of energy used divided by the maximum possible to be used. These definitions are equivalent.
Capacity factor. The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over ...
