TBM 900 Aerodynamics


Airframe Design

The TBM 900 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 900 airframe builds on the success of the TBM 850 and the TBM 700.


TBM 900 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 900 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 new wingtips give the TBM 900 its new signature look and coupled with aerodynamic improvements to the ailerons, vertical stabilizer and new inner gear doors significantly reduce drag while improving low speed and high angle of attack handling in flight.


New Tail Cone and Light

The TBM 900 tail cone has been restructured making it more streamlined reducing drag and improving airframe efficiency. To improve visibiliy at night, Socata added an additional light at the tip of the tail of the aircraft. This gives improved lighting around the TBM900 to enhance visibility of the TBM 900 by other aircraft in low-light conditions.


New Gear Doors

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 900 adds an inner gear door, which reduced turbulence and improves its aerodynamic efficiency.
