名詞

A device that alters the aerodynamics of an airplane, glider etc, allowing it to descend quickly but safely, especially when caught in a thermal

日本語の意味

航空機やグライダーなどがサーマル（上昇気流）の影響下で急激に高度を落とす際に、安全に下降できるように空力特性を変化させる装置。

When the glider became trapped in a rising column, the instructor urged the student to deploy the dethermalizer to ensure a rapid but safe descent.

One of the most bittersweet joys in model aviation is an out of sight flight by a Free Flight model. While we all strive for our models to fly as well as we can, it is possible to have a model fly too well. Well trimmed, and with a bit of luck, a model can be caught in a thermal and climb to beyond the limits of our vision. It is the purpose of a dethermalizer to effect a change in the geometry of a model, such that it descends more rapidly, yet still safely. Getting the DT to activate after a target time is the job of a DT timer. ~ Thayer Syme. Reprinted with permission.
