The TBM 930 airframe design employs several fail-safe structural design techniques, including the use of multiple load paths and a crack-stopper band to maximize sub-system reliability/durability and structural life. The TBM 930 airframe builds on the success of the previous TBM models.
TBM 930 airframe designers carefully chose a variety of aluminum alloys, high strength steel (including titanium) as well as advanced composite materials to maximize structural strength and durability, while minimizing not only aircraft weight but also acquisition and life-cycle support costs. The majority of the TBM structure is manufactured from conventional aluminum alloys. The exceptionally strong wing spars, flap tracks and windshield frames are machined from solid bars of aluminum.
The TBM 930 uses advanced composite materials such as carbon fiber for its winglets and its enhanced cowlings which maximize its structural strength and durability while minimizing weight.
Composite 2ft High Winglets
The 2-foot high winglets immediately become the signature of the TBM 930. Coupled with aerodynamic improvements to the ailerons, vertical stabilizer and new inner gear doors, these winglets significantly reduce drag while improving handling at low speeds and high angles of attack.
Tail Cone and Light
The TBM 930 tail cone has been restructured making it more streamlined reducing drag and improving airframe efficiency. To improve visibility at night, Daher added an additional light at the tip of the tail of the aircraft. This gives improved lighting around the TBM 930 to enhance visibility of the TBM 930 by other aircraft in low-light conditions.
Computational Fluid Dynamics (CFD) analysis of the airflow over the previous TBM airframe revealed a significant amount of turbulence in the area of the gear doors. The TBM 930 adds an inner gear door, which reduced turbulence and improves its aerodynamic efficiency.
