Problems solved by technology

However, given the ability to achieve short takeoff distances, existing blown-lift STOL aircraft designs tend towards light wing loading, which can make the aircraft more susceptible to wind disturbances and lead to lower control during landing
Therefore, the need for greater landing distances due to lower control over landing dispersion may limit the application of existing blown-lift STOL aircraft

Abstract

The title of the invention is fixed-wing short-takeoff-and-landing aircraft and related methods. The aircraft comprise an airframe comprising a rear wing assembly and a forward wing assembly positioned forward of the rear wing assembly, a rear plurality of blowing rotor assemblies operatively coupled to the rear wing assembly that are configured to blow air across the rear wing assembly to induce lift in the rear wing assembly, and a forward plurality of blowing rotor assemblies that are operatively coupled to the forward wing assembly and configured to blow air across the forward wing assembly to induce lift in the forward wing assembly. The methods comprise inducing lift in a forward wing assembly by blowing air across the forward wing assembly with a forward plurality of blowing rotor assemblies and inducing lift in a rear wing assembly by blowing air across a rear wing assembly with a rear plurality of blowing rotor assemblies.

Description

technical field [0001] This disclosure relates generally to STOL aircraft. Background technique [0002] In the aviation industry, there is a strong and growing interest in aircraft that can take off and land without the use of large runways. For example, a variety of military and urban air mobility operations wish to utilize aviation in environments that do not provide the length of runways required for conventional fixed-wing aircraft to take off and land. Traditionally, the need for aircraft that can operate without the use of large runways has been addressed by vertical take-off and landing (VTOL) aircraft such as helicopters, multi-rotors, and compound rotor and wing configurations where lift is achieved through lift rotors. Although VTOL aircraft can take off and land without a runway, VTOL aircraft are generally less efficient, operate at lower flight speeds, and generate high levels of noise relative to fixed-wing aircraft.
