A platform for an airfoil in a gas turbine engine is provided. The platform includes a top wall configured to connect to an airfoil of the gas turbine engine, two sidewalls extending downward from the top wall a connector attached to and connecting the two sidewalls, wherein the top wall, the sidewalls, and the connector define an interior volume of the platform, and a single stiffener extending from the connector to the top wall within the interior volume between the two sidewalls. The connector defines two parallel apertures passing through the connector.

A platform for an airfoil in a gas turbine engine, the platform comprising: a top wall configured to connect to an airfoil of the gas turbine engine;two sidewalls extending downward from the top wall;a connector attached to and connecting the two sidewalls, wherein the top wall, the sidewalls, and the connector define an interior volume of the platform; anda single stiffener extending from the connector to the top wall within the interior volume between the two sidewalls,wherein the connector defines two parallel apertures passing through the connector,wherein the platform has a front end and a rear end, and wherein the two parallel apertures extend through the connector from the front end to the rear end. 2. The platform of claim 1, wherein the two parallel apertures are configured to receive substantially identical pins therethrough. 3. The platform of claim 2, further comprising two substantially identical pins installed in the two parallel apertures. 4. The platform of claim 1, wherein the stiffener is connected to the connector at a point between the two parallel apertures of the connector. 5. The platform of claim 1, wherein the connector defines a bottom wall ofthe platform. 6. A method of manufacturing a platform for an airfoil in a gas turbine engine, the method comprising: forming a connector of a platform with two parallel apertures passing therethrough;forming two sidewalls extending upward from the connector;forming a top wall opposite the connector, wherein the top wall, the sidewalls, and the connector define an interior volume of the platform; andforming a single stiffener extending from the top wall to the connector within the interior volume between the two sidewalls,wherein the platform has a front end and a rear end, and wherein the two parallel apertures are formed to extend through the connector from the front end to the rear end. 7. The method of claim 6, wherein the two parallel apertures are formed to receive substantially identical pins therethrough. 8. The method of claim 7, further comprising installing two substantially identical pins through the two parallel apertures. 9. The method of claim 6, wherein the stiffener is formed to connect to the connector at a point between the two parallel apertures of the connector. 10. The method of claim 6, wherein the connector defines a bottom wall of the platform. 11. The method of claim 6, wherein the top wall, the sidewall, the connector, and the stiffener are formed simultaneously. 12. The method of claim 6, wherein the top wall, the sidewall, the connector, and the stiffener are formed by a layup process. 13. A gas turbine engine comprising: a rotor;at least one airfoil; anda platform configured to connect the at least one airfoil to the rotor, the platform comprising: a top wall configured to connect to an airfoil of the gas turbine engine;two sidewalls extending downward from the top wall;a connector attached to and connecting the two sidewalls, wherein the top wall, the sidewalls, and the connector define an interior volume of the platform; anda single stiffener extending from the connector to the top wall within the interior volume between the two sidewalls,wherein the connector defines two parallel apertures passing through the connector,wherein the platform has a front end and a rear end, and wherein the two parallel apertures extend through the connector from the front end to the rear end. 14. The gas turbine engine of claim 13, wherein the two parallel apertures are configured to receive substantially identical pins therethrough. 15. The gas turbine engine of claim 14, further comprising two substantially identical pins installed in the two parallel apertures. 16. The gas turbine engine of claim 13, wherein the stiffener is connected to the connector at a point between the two parallel apertures of the connector. 17. The gas turbine engine of claim 13, wherein the connector defines a bottom wall of the platform.
