Analytical Vehicle Definition

Vehicle definition is defined by:1) Requirements flowdown2) Technology capability3) Affordability) y

Requirements and technology define the subsystem / component capabilit S bs stem / componentcomponent capability. Subsystem / component capabilities define the air vehicle capabilities, while CAIV (Cost As an Independent Variable) determines executability

Next Platform Problem Statement

Assumption – should be a step-function improvement i i l bili d ff iin operational capability and effectiveness

The size of the step dictates the configuration whichThe size of the step dictates the configuration, which drives the technology. Technology can be an enabler or inhibitor

We need to be developing the enabling technologies NOW to meet a 2025 capability

Active Flow Control (AFC)

Overall objectivesTo improve the high-lift performance of a helicopter rotor blade in high-speed forward and mane er flight

Candidate US Army/NASA rotor hubs

and maneuver flightTo demonstrate the ability to alleviate shock wave high-speed impulsive (HSI) noise

Technology Approach:These objectives are met through the use ofThese objectives are met through the use of on-blade active flow control (AFC) using an array of oscillatory “zero-net-mass jets”

Demonstrate the aerodynamic performanceProgrammatics/Approach:

Demonstrate the aerodynamic performance benefits of Active Flow Control (AFC) for a two-bladed small-scale active rotor (SSAR) for conditions representative of high-speed forward flightDemonstrate that on-blade active flow controlDemonstrate that on blade active flow control results in:

an increase in maximum rotor thrust capability, anda reduction in rotor power without adverse effects
