“…There are two main methods for stabilizing the pitch on missiles. The first is with the use of nose mounted canards and nose flaps which can be very stable at higher Mach numbers (12). The second method utilizes the location of the fins that extend from body slots to affect the longitudinal stability.…”

The main objective of this research was to design and develop a planform shape for a single passenger, unpowered, subsonic glider that relies on gravitational forces for momentum. The wing structure and aerodynamic shape optimized the benefits of near-ground flight (i.e. the increased lift and decreased induced drag), and as a result reduced the overall aircraft weight and wingspan, and enhanced the maneuverability of the craft.

Forebody Articulation at High Angles of Incidence

et al. 2023

An experimental investigation was carried out to understand the effect of forebody articulation on the aerodynamic characteristics and the flowfield development over a slender body at high angles of incidence. The experiments were carried out at the Florida A&M University and Florida State University low-speed wind tunnel over a range of forebody deflection ([Formula: see text], [Formula: see text], and [Formula: see text]) and flow conditions. The results show that a positive forebody deflection increases the normal-force coefficient, whereas a negative forebody deflection decreases the normal-force coefficient at high angles of incidence. Pitching moment characteristics showed that all forebody deflections tested produce a pitching moment despite minimal normal force at low angles of incidence. Lateral aerodynamic characteristics showed that the side-force onset angle does not solely depend on the semi-apex angle of the forebody (as predicted for axisymmetric slender bodies), and the role of the forebody-to-aftbody transition geometry in initiating vortex asymmetry is equally important. The particle image velocimetry results show that a positive forebody deflection increases the size, strength, and circulation of the vortices developing on the body, leading to an increase in aerodynamic forces and moments. The flowfield development for a negative forebody deflection is dominated by secondary shear-layer vortices originating from the forebody to aftbody junction.
