description abstract	An investigation was made in the Langley 300 MPH 7- by 10-foot tunnel and the Langley gust tunnel to determine the static longitudinal aerodynamic characteristics and the gust-alleviation capabilities of forward-located (at 12 percent chord) fixed spoilers, deflectors, or a spoiler-deflector combination on a simulated transport airplane model having an unswept wing. The lift-curve slopes are fairly linear and are substantially reduced by the addition of either the spoiler or deflector configuration; however, the lift-curve slope was nonlinear for the spoiler-deflector combination. Extending the deflectors necessitates only small changes in attitude and trim in order to maintain a given lift coefficient, whereas extending the spoiler or the spoiler-deflector combination requires large changes.
