As specialists in aerodynamic and aeronautical structures, Albatross Aeronautics provides engineering services regarding these areas.
Our team has a wide experience in Testing and Certification. Testing is actually a requirement to certificate a product or a design, particularly relevant in aeronautics. Moreover, Tests are necessary to improve the reliability, economy, design and other parameters of a product; and also to validate computational models for stress, aerodynamics and so on.
Certification and testing is itself an activity that consists in management of all the acitvities needed to comply with applicable requirements. It includes the process from the very conception of the aircraft to the final test and report, and comprises the activities of normative interpretation, prototype manufacturing and instrumentation, coordination with all the necessary actors, and finally laboratory testing and monitoring. Tipically any mistake during testing phase will have desproportionate costs, and experience in this phase as well as proper knowledge of the laboratories is key to achieve the best result both in cost as in schedule.
To provide these services to our customers, our team has many years of experience working in the management and execution of Tests, Certification of structures and aeronautical and Wind turbine materials.
Our team has more than 20 years accumulated in the most diverse areas of aeronautical, structural testing, both in composite and metallic parts, certifiying according to FAR/CS 21, 25, 27 and 29. Namely, all the aeronautical certification normatives.
Tightly joined to testing technology for model validation, Aerodynamics and fluid mechanics is a very exclusive area of engineering with wide application. Due to its mathematical and physical complexity, it is not available to the industry in general at a reasonable cost. As results of the experience in the design of Antares as well as vertical and horizontal axis wind turbines, with stationary or time-dependent models, Albatross Aeronautics engineers have a fairly wide know-how in fluid mechanics as well as the fields associated and related to it, as themal fluid analysis, combustion, and heat transfer phenomenons.
In Albatross the first step to a proper aerodynamical model is the theoretical study of the problem and later the mathematical modelling via manual calculations and Matlab implementation. Further refinement is achieved through specific software such as FineOPEN, Star CCM and COMSOL.
Stress and design are necessary tasks for the accomplishment of any technological project. Although Albatross main expertise area is not the structural detailed computation, the more rare conceptual design from scratch is the main ability of our engineering team. Besides, through our quite expert collaborators in the area we can supply extensive FEM modelling capabilities that enable us to calculate particularly critical parts of the airplane as to avoid risk of loss of the UAV during critical maneouvres of flight. Software used includes CATIA ELFINI for standar problems, NASTRAN/PATRAN for specific problems requiring a more powerful tool, and ABAQUS for non-linear behavior of composite structures.
Nowadays the design and manufacturing trends in wind turbines follow the concept of “big size wind turbine”, leaving the mini-eolic ones aside. In particular, the current designs are neither efficient nor optimized for places with turbulent and low intensity winds.
Albatross has developed the aerodinamical design low-power wind turbine for urban environments adapted to this application. Detailed study of wind behavior in complex urbane terrain shows that turbulence requires a different, specific design for a proper performance. The characteristic low Reynolds number at which such inventions operate make them a challenge for the aerodynamical engineer, and new tools have been developed in order to cope with these problems. Working with technological centres devoted to green energy, Albatross has developed a 1.5 KW and a 7 KW VAWT, both of them now ready for performance testing.
The VAWT (Vertical Axis Wind Turbine) aerodynamic operational concept is, together with helicopter rotor design, the most complex mechanism that presents a hard challenge to the aerodynamical engineer when a good target in terms of energy draw prediction is required. Besides, the cyclic nature of the blade rotation together with the turbulence characteristics make of the VAWT one of the most complicated design in machines known.
Albatross Aeronautics has developed specifical aerodynamical model for this kind of wind turbine in order to determine the output power, most efficient aerodynamic airfoil and configuration, and overall efficiency of the machine. The possibility of investigation is much higher having developed a mathematical model specific for this application. When properly run, the model can achieve precise results in a timelap of some minutes, when a typical CFD sample would take as much as several weeks to analyze a single configuration. Using the computational efficiency of the model, a parametric study of all the relevant features of the wind turbines has been performed in order to optimize it in accordance with the ones required by the customer, finally obtaining a fully functional, ecological and aesthetic product.Back to top
Albatross Aeronautics has provided several training courses, both for big private companies and public institutions (universities). We provide training courses in specific areas, as well as prepare courses ad hoc for the customer. We currently provide training courses in the following areas :
Instrumentation engineering is essential in any test as it is necessary to monitor the results of the tests performed in a realiable way. It includes the selection and implementation of Data Acquisition Systems, communication with, and the installation of the sensors. When installing up to several hundred of sensors, instrumentation engineering becomes an art and experience is key to avoid unecessary, costly delays in prototyping.
Having a highly qualified team with a wide experience in design and carrying out Test Instrumentations, Albatross Aeronautics has the capability to perform instrumentations for any structure, from small test parts with a few channels to big assemblies with hundreds of channels with special condition environments such as flight test instrumentations, salt water conditions, so on.
Either short or long time, indoor or in-flight, quasistatic or high frequency tests, we are able to integrate multiple sensors with external signals and universal timers with DAQs in accordance with the customer needs.
The design of the electronic systems of the project Antares has been developed after realizing an exhaustive analysis of the products that exist on the market and it has been based on the most advanced technologies on the fields of electronics and systems.
The auto-pilot systems are made up of centrales inerciales, GPS, altimeter, pitots, internal sensors (fuel gauge,rpm,etc..)
The auto-pilot management procedures are based on a hybridation system of IMU, GPS .and barometrical altimeters (to obtain the altitude in every moment of the flight. In addition, there are two control loops for the flight monitoring and the navigation management. This system is based on GNC Technology (Guidance, navigation and Control Technology).
The Hardware is based on a embedded system, connected to various types of sensors and actuators. The elements that conform the Auto-pilot have been selected to guarantee an architecture estructured in independent modules. This kind of architecture makes easier to introduce improvementes in each module. Likewise, this type of estructure provide more flexibility and allows to include new equipment for a better adaptation to the requirements of different missions.
The software is based on concurrent processes in real time that obtain information from each sensor in parallel. In turn, according to the information received from the sensors, the processes that have been developed send the appropriate signal to the actuators (rudder, flaps, accelerator,etc..) to guarantee the equipment stability and the fulfillment of the mission.
Our design can be easily adapted to each specific client requirements and for each mission or type of aircraft. To comply with the new specifications, solely would be necessary to replace certain devices and to adapt the software for a complete integration of the elements in the global architecture.
Albatross Aeronautics offers a depth and breadth of services and customized solutions depending on the needs of the client, making possible to include new elements (chemical sensors, thermal cameras,etc..) and new aircraft models in a swift and economic way.
Albatross AeronautIcs has personnel specialized in the design, development and implementation of solutions adapted to the needs of each client.
