Landing Gear is proved to be the most critical subsystems in aircraft. It is a crucial part in all ground operations, takeoff and landing of aeroplane. Landing gear operates as dead weight after an aircraft is in the air, burning more fuel and taking up room which can be used for other safety measures. When taking into account all the legal and safety standards, it is vital to shorten the time needed for the landing gear design and its development cycle. All aerospace sectors strive for attributes such as minimal weight and volume, great performance, and reduced life cycle costs. Our objective was to create a landing gear with the least amount of weight and volume while maintaining maximum structural integrity. To achieve this goal, we designed landing gear links using generative design. In addition to this, we also studied different parameters considered for landing gear design.

Combining evolutionary algorithms with additive manufacturing (AM) techniques, new material approaches, in aerospace and industrial applications can result in advanced design procedures. This combination adds extra degrees of flexibility to the final design concept, enabling multifunctional designs. Aerospace, which is heavily focused on customised production, is a perfect fit for AM due to its effects on economies of scale and scope. These technologies are prepared to be included within the generative design process for safety-critical contexts, including the aerospace, thanks to novel structural materials and advanced AM processes. The three primary phases of conventional aircraft design are conceptual design, preliminary design, and detailed design. Multidisciplinary optimization processes are currently being developed to support designer in assessing the optimal solution. Generative Design is a novel form-finding process that takes into account structural performance, material properties and ergonomic demand. Evolutionary design approaches limits to numerical optimization, while Topology Optimization seeks to find an optimal structural configuration within a given design domain for specified objectives, constraints, loads and boundary conditions. This paper focuses on creating appropriate generative design models which can sustain same amount of stresses as of the original model. In the current study the optimization of Boeing 747’s nose landing gear is depicted using solidworks and fusion 360. Static structural analysis is utilized to evaluate the effects of stresses and failure mode produced by various materials, in order to figure out a materials characteristic as well as for material selection. Additionally, this paper examines original and generative design models

The world is facing a huge energy crisis due to resources depletion. The renewable energies play a vital role in energy generation sector. Fossil fuels such as coal and oil cause enormous environmental pollution. Wind energy is a major renewable source of energy and can replace this fossil energy. This paper aims to study the energy generation methods using roof ventilators. A wind driven, having metallic construction and blades on its periphery is a roof top ventilator. It is installed on the roof of industries as well as machine shops, warehouse and it provide effective ventilation. Hot air becomes lighter and goes upward on the top of industries and is expelled out through ventilator. At the same time fresh air also suck inside due to free spinning of roof ventilator. This free spinning can be converted into electrical energy using different electrical components. This technique is low in cost and feasible because of the minimum quantity of transferring elements and electric systems.

As humanity is moving towards becoming a multi-planetary civilization, it is very important to make efficient use of resources available on our planet first and then head towards exploiting the resources of another celestial body. It is also important to cause minimum harm to the space environment around our planet as well as the planetary atmosphere. Advancement in conventional rocket fuel is one of the ways to optimize the consumption of fuel during a space launch but it cannot always be feasible. Finding cheaper alternatives like Biofuels can also be a significant point of discussion. Such fuels can be naturally obtained without much harm to the environment and they can be as effective as conventional rocket fuel. For complete sustainability, not only internal changes but also external changes should be considered. To attain space sustainability, we need to follow a technology-driven approach while considering the cost and effective management of the space missions. This paper is a review of various techniques involved in the sustainable development of space vehicles, and effects of existing techniques involved during the launch of the space vehicle.
