Aircraft
Shortly after rotation; smoke entered the cockpit and cabin. The smoke smelled like something was burning and a high pitched whistling noise began. ATC was notified. ATC cleared us to land on the opposite runway. We quickly donned our oxygen masks and performed a teardrop maneuver to land on the opposing runway.  As we lined up with the runway the smoke began to dissipate however our environment system was not providing cool air. A normal landing was made and vehicles inspected the exterior of the aircraft. When given all clear we taxied back to the FBO and shutdown. Maintenance was notified and the airplane was grounded until released.
