Adding backup engines to enhance aircraft safety

Abstract

Some commercial aircraft occasionally experience issues related to engine failure, which presents a significant challenge in the field of aviation. There are multiple causes that may lead to such failures, the most prominent of which is the aircraft's collision with a flock of birds. Despite major advancements in technology, this problem continues to pose a threat to aircraft worldwide. From this standpoint, the need has emerged for adding backup engines that can be automatically activated in emergency situations to ensure continuous flight and maintain control of the aircraft. The invention also addresses issues related to increased weight and fuel consumption resulting from the addition of auxiliary engines.

[0001] Title: Adding Auxiliary Engines to Enhance Aircraft Safety

[0002] Detailed Description:

[0003] Background of the Invention:

[0004] This invention aims to address some of the security and operational challenges faced by commercial aircraft in emergency situations, particularly in the event of a primary engine failure. One of the most significant risks aircraft face is flying with only one engine, which leads to a substantial decrease in performance and maneuverability, especially In adverse weather conditions or during emergencies. Furthermore, relying on the backup power unit (APU) can be problematic due to Its failure, potentially compromising the aircraft's essential systems. In such circumstances, the aircraft becomes less able to control its course, potentially endangering passengers and the aircraft itself.

[0005] It is crucial to modify the aircraft's systems without sacrificing the entire aircraft.

[0006] This is why the need arose to add backup engines that can be automatically activated in emergencies to ensure continued flight and aircraft control without significantly impacting operational efficiency or fuel consumption.

[0007] The invention also addresses issues related to aircraft weight balance and fuel efficiency by designing backup engines that operate idle during normal flights, thus reducing fuel consumption and maintaining operational economy. Overall, this innovation addresses numerous concerns regarding aviation safety in emergency situations and aims to improve safety in commercial aviation while enhancing operational efficiency.

[0008] In a thorough examination of existing technologies and previous attempts to address bird strikes and engine failures In flight, no comprehensive technological solutions have been found that provide sufficient safety to tackle these challenges. While some studies and innovations address specific aspects of these problems, most do not offer effective solutions to mitigate the risks posed by bird strikes or engine failures during critical phases of flight. Current research has revealed a lack of advanced technological solutions that encompass all aspects of these issues, both in terms of prevention and recovery from engine failure. This necessitates the development of new technologies based on advanced sensing technologies or innovations in materials and mechanical systems. Status of Previous Technologies:

[0009] 1. Details of Previous Technologies: Some innovations that may have existed but were not comprehensive or sufficiently effective were mentioned.

[0010] 2. Alternative Solutions: It was clarified that alternative solutions were insufficient for both prevention and emergency response.

[0011] 3. Although some research exists on hybrid systems, no known existing technology adds Actual, medium-powered backup engines, operating in idle mode and activated only in emergencies, with full integration of intelligent control systems and weight and interior space adjustments as described in this innovation.

[0012] Detailed Description:This innovation is based on adding backup engines to commercial aircraft, employing flexible solutions to the problems of weight and fuel consumption. This innovation aims to enhance flight safety in extreme emergencies and achieve a higher level of passenger safety without significantly impacting aircraft efficiency or operating economy. As a strategic option, these backup engines provide additional safety systems that ensure continued flight and complete control in the event of the failure of one or both primary engines, while maintaining the aircraft's basic function and performance.

[0013] Aircraft Engineering Design:

[0014] 1. Auxiliary Engines:

[0015] 1.1 Two auxiliary medium-power engines are strategically added, as shown in Figure 1-A, so as not to affect the aircraft's aerodynamics or balance, either at the rear of the aircraft (1) or alongside the primary engine (2) under the wing.

[0016] 1.2 Idle Operation: The engines operate in idle made during normal flight to reduce fuel consumption and minimize performance impact.

[0017] 1.3 Activation When Needed: The engines are activated only in emergencies, such as the complete failure of the main engines, or one of them, to ensure continued flight and control of the course.

[0018] 2. Weight and Fuel Solutions:

[0019] 2.1 Fuel: Since the engines operate at idle most of the time, they do not require additional fuel. The fuel allocation is as planned for the aircraft, keeping in mind that the backup engines will only consume fuel in emergencies.

[0020] 2.2 Weight Solution: To reduce the weight generated by the engines, some seats can be removed or the number of passengers reduced, which maintains the aircraft's balance and enhances performance and control.

[0021] 2.3 Dynamic Adjustment: Studying the modification of baggage areas or passenger distribution to accommodate the size of the backup engines to Improve the aircraft's balance and efficiency.

[0022] 3. Utilizing Seat Space:

[0023] 3.1 Some of the seat space can be utilized to add essential services such as a mini-hospital or additional facilities like lavatories or medical rooms, in accordance with the aircraft's weight and passenger comfort requirements.

[0024] 4. Intelligent Operating and Control Systems:

[0025] 4.1 Developing intelligent electronic systems to automatically activate the backup engines in the event of a primary engine failure.

[0026] 4.2 Automatic Control: Immediate activation of the backup engines to restore flight capability and control speed. Altitude.

[0027] 4.3 Safe Landing: Enabling the aircraft to land safely using backup systems without complex pilot intervention.

[0028] 4.4 Integration with Other Systems: Integration with autopilot and navigation systems to ensure arapid and effective response.

[0029] Risks Associated with Flying on Only One Engine:

[0030] Not Installing Additional Engines with a Backup Power Unit (APU)

[0031] 1. Risks Resulting from Reliance on the Backup Power Unit (APU):

[0032] 11 Some aircraft are equipped with a Backup Power Unit (APU), a small device that provides electricity and power to critical equipment during flight. Although the APU is not used to propel the aircraft, it
