Patent ID: 8602351

Claim:
A removable horizontal stabilizer configured to provide aerodynamic stability for a rotorcraft having a tailboom, the horizontal stabilizer comprising: a spar configured to be transversely located at least partially inside an opening in the tailboom; a first horizontal airfoil adapted to fittingly receive the spar; a second horizontal airfoil adapted to fittingly receive the spar; a removable spar attachment member configured to structurally attach the spar to the tailboom; a first removable airfoil attachment member configured to structurally attach the first horizontal airfoil to the spar; a second removable airfoil attachment member configured to structurally attach the second horizontal airfoil to the spar; a first bonding strap removably fastened to the first horizontal airfoil for providing a ground path between the first horizontal airfoil and the tailboom; and a second bonding strap removably fastened to the second horizontal airfoil for providing a ground path between the second horizontal airfoil and the tailboom; wherein the first and second horizontal airfoils extend outboard from the tailboom so as to provide aerodynamic pitch stability; wherein the spar is configured to provide structural support for the first and second horizontal airfoils.
