![]() “Our thoughts and prayers are with the family during this difficult time. “We are saddened to hear about the tragic loss of a team member of the AA/Piedmont Airlines,” the airport’s executive director, Wade Davis, said at the time. That aircraft, an Embraer 170 operated by regional carrier Envoy Air, was “parked at the gate with the parking brake set when a ground support personnel was ingested,” said the agency. Drag is directed along and opposed to the flight direction. The air resists the motion of the aircraft and the resistance force is called drag. While police and other officials continue to investigate this incident, we defer to them on providing further details.”Īn airport worker who died in an accident at the Montgomery Regional Airport in Alabama last New Year’s Eve also was ingested into the engine of an aircraft, the NTSB said in a January statement. Drag As the airplane moves through the air, there is another aerodynamic force present. Out of respect for the deceased, we will not be sharing any additional information. Determining drag by the accelerometer method requires the accurate measurement of longitudinal and normal accelerations, angle of attack, and engine thrust. ![]() “From our initial investigation, this incident was unrelated to Unifi’s operational processes, safety procedures and policies. “Our hearts go out to the family of the deceased, and we remain focused on supporting our employees on the ground and ensuring they are being taken care of during this time,” the company said in a statement to CNN. Unifi Aviation provides aviation services at San Antonio International Airport and employed the worker who died. If your airplane was shaped like a shoe box it will have more form drag than if it was more. This tutorial will provide you with the tools to construct your own. Form drag is the result of the relative airflow moving over a shape. Our hearts and full support are with their family, friends and loved ones during this difficult time,” a Delta spokesperson told CNN in an email. The drag polar is a fundamental aspect of aircraft design and performance analysis. “We are heartbroken and grieving the loss of an aviation family member’s life in San Antonio. We will share more information as details become available.”ĭelta Air Lines said it was “grieving” the loss. This, in physics terms, is how balance is achieved the air acts as an upward force on the plane, hence lift, and the weight and mass acts as a downward force, hence drag. “We are deeply saddened by this incident and are working with authorities as they begin their investigation. “An accident occurred on the ground at San Antonio International Airport (SAT) Friday night that resulted in the fatality of an airline ground crew member,” airport spokesperson Erin Rodriguez said in a statement. The spokesperson added the airline is "fully supporting ongoing investigations".Montgomery, Alabama, airport worker died after being 'ingested' into aircraft engine, NTSB says "Our hearts and full support are with their family, friends and loved ones during this difficult time." How is drag generated Drag is a mechanical force. Drag is generated by every part of the airplane, even the engines. ![]() "We will share more information as details become available."Ī spokesperson for Delta said: "We are heartbroken and grieving the loss of an aviation family member's life in San Antonio. Drag is the aerodynamic force that opposes an aircraft’s motion through the air. In a statement, San Antonio International Airport said: "We are deeply saddened by this incident and are working with authorities as they begin their investigation. The airport worker was employed by Unifi, a company Delta shares a contract with to support ground handling operations. In the case of an airplane, air resists the forward motion of the airplane. While the 4 forces oppose each other, they don. All are equally important, and they must be balanced to maintain level flight. Lift and weight are opposing forces, as are thrust and drag. The forces all interact together to determine an airplane’s trajectory. The NTSB said that it is "continuing to gather information about the event". When two masses are in contact, they resist each others motion. The four forces making up the principle of flight are lift, weight, drag, and thrust. ![]() It had flown into San Antonio in Texas from Los Angeles. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditional propeller engines. ![]() The employee, who has not been named, was sucked into the engine of a Delta Air Lines flight at San Antonio International Airport, last Friday, according to the National Transportation Safety Board (NTSB).ĭelta Flight 1111 was taxiing to its gate with one engine turned on when the incident took place at around 10.25pm local time. How do planes fly If youve ever watched a jet plane taking off or coming in to land, the first thing youll have noticed is the noise of the engines. An airport worker in the US has died after being "ingested" into a passenger plane engine, officials have said. ![]()
