- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.� License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.��NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: NASA's Langley Research Center has created a novel process that significantly improves the effectiveness of high-lift devices on aircraft wings by utilizing a hybrid concept of both sweeping jet (SWJ) actuators for active flow control (AFC) and adaptive vortex generators (AVGs) for passive flow control.� High-lift technology re-shapes aircraft wings for more lift during takeoff and landing.� Conventional high-lift devices are complex and employ a significant number of parts. In addition, these complex mechanical high-lift systems (e.g., Fowler flap mechanisms) often protrude externally under the wings, resulting in increased cruise drag.� Simple hinged flaps are preferable high-lift devices for low-drag cruise performance, but they are vulnerable to flow separation at high flap deflections for both trailing edge and leading edge applications.� This innovation achieves higher flap deflections without flow separation while minimizing the pneumatic power requirement of AFC. The combination of AVGs with SWJ actuators creates an unparalleled and unexpected improvement in flap efficiency. This unique hybrid approach of using SWJ actuators and AVGs in combination may provide the necessary lift enhancement for a simple hinged flap high-lift system while keeping the pneumatic power requirement (mass flow and pressure) for the SWJ actuators within an aircrafts capability for system integration.� For the current innovation, it is envisioned that this hybrid approach may significantly narrow/close the technology gap and enable the realization of a simple hinged flap high-lift design, which will have the benefits of lower weight (without the Fowler flap mechanism) and less cruise drag (without the external fairing for the Fowler flap mechanism).� Figure 1 illustrates one example of how AVGs and the SWJ actuators can be used in combination for a simple hinged flap high-lift system.� For high-lift applications with a high flap deflection angle and a significant adverse pressure gradient, both SWJs and AVGs are activated for hybrid flow separation control.� When the flap is deflected to a low deflection angle, only AVGs are activated to prevent possible flow separation initiated from the trailing edge.� Figure 2 shows the cruise configuration with no flap deflection and there is no flow control activation. To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/LAR-TOPS-117 If you have any questions, please contact Langley Research Center at LARC-DL-technologygateway@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.� For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.��No follow-on procurement is expected to result from responses to this Notice.
