1 configuration by providing simplified launch, deep stall
landing, all- environment capability, longer endurance, updated sensor payloads and operation using Lockheed Martin's mobile ground control system.
Recovery involves a deep stall
maneuver, landing on a small inflatable cushion.
This action recovered the aircraft from the deep stall
In fact, almost no other aerodynamic system operates in deep stall
Post-crash investigation concluded the prototype 1-11 had experienced an unrecoverable deep stall in which the wake of the stalled wing covered the high-mounted horizontal stabilizer, thus blanking the elevator controls and preventing normal recovery techniques.
This is known as a "locked-in deep stall," and it's a sure-fire way to ruin a pilot's day.
Whereas the Pointer makes a soft horizontal landing (facilitated by having the propeller in a pusher arrangement behind the high-set wing), the Raven is recovered by inducing a deep stall, leading to a vertical landing.
A deep stall recovery allows the drone to be retrieved accurately, which is vital in special operations.
Like most aircraft of this category, flight is preplanned but alterable, and landing is belly or deep stall
Upon landing the Pointer performs a deep stall
and falls vertically, retaining its equilibrium to the land softly.
It has extra deep stalls
, built-in muzzle blast barriers, integrated lighting and floor-to-ceiling walls to provide shooters with a comfortable atmosphere.
Key to understanding stalls, of course, is knowing why and how they occur, why we practice them and how we can use the knowledge and experience gained during that practice to prevent more dramatic behavior, like deep stalls
or spins, especially when close to the ground.
