Adaptronica is the leader of the consortium, which carries out a national research project within the framework of the Operational Program Intelligent Development, Sectorial R&D Programs, INNOSBZ, managed by the National Center for Research and Development. Project title: “ADBAG – Adaptive airbags for emergency landing of unmanned aerial vehicles”, POIR.01.02.00-00-0083/16.
The ADBAG project aims at development of an adaptive airbag system for a drone weighing up to 10 kg. The task of the adaptive airbag is twofold. First, the adaptive airbag system protects people or ground infrastructure from being struck by the drone in the event of its failure. Second, it protects against the destruction of the drone itself. This is especially important when there is valuable equipment or data on the board.
The adaptability of the system to be developed consists in adapting the airbag mode to the anticipated kinetic energy of the drone right before the impact with an object. Thanks to this feature, the system provides smooth landing for falls from different heights.
The adaptive airbag system, developed for the drone, can be rescaled for use in other aircraft of larger mass e.g. in the ULL-class ultralight aircraft.

Smart sensors and actuators
Adaptronica Sp. z o.o. carries out a national research project – “ADAC System for stabilization of vibrations in satellite structures”, the Agreement No. 01.02.00-14-5731/16, within the framework of the Regional Operational Program – Mazovia Region 2014-2020, “R&D activity of enterprises”, managed by the Mazovian Center for EU Funds Distribution. Project Total value: 1.390.776,00 PLN. Project Grant value: 1.023.360,00 PLN. Project Duration: 2017-2018.
The ADAC project aims at development of a solution to stabilize the vibrations of satellite and spacecraft structures, both orbiters and landers. The ADAC solution is based on the PAR (Prestress-Accumulation/Release) concept of damping of vibrations induced by an impact on skeletal structures. It takes advantage of an innovative adaptive clutch, which allows for quick switching from the frame to truss mode of node operation.
With ADAC, the satellite structure and the optical or measuring devices installed on it, will have a longer lifespan and more accuracy. The most important result of the project will be the implementation of the ADAC system. Adaptronica plans to enter the chain of suppliers of the space industry large integrators, extend international activities and increase the competitiveness of the Polish space sector.
The proposed ADAC solution is primarily a response to the needs of the space industry. However, it can also find other terrestrial applications such as image stabilization, vibration damping of industrial machines or equipment in bioengineering.

Semi-active damping of vibrations - PA-R system
The semi-active system for vibration suppression, the so called PA–R System (Prestress Accumulation – Release) is a combination of the vibration damping strategy and the implementation of this strategy in the form of an adaptive clutch. Taking advantage of the Prestress Accumulation–Release (PA–R) strategy, over 95 % of the vibration amplitude can be attenuated in only few cycles of oscillation, by appropriate switching of PAR Nodes to compliant mode of operation. The adaptive clutches of appropriate size can be installed in frame-truss structures to modify the response. A vibration sensor and a dedicated controller adjust stiffness of adaptive clutches in order to achieve superb vibration suppression without providing external mechanical energy into the structure. Only the electrical power for the system is necessary. The efficiency of the PA–R system was presented in an example of the demonstrator structure in the form of a cantilever frame with a length of about 1.20 m.
Main advantages of the PA–R System:
The adaptive clutch is a mechanical interface between structural members, capable of adjusting the bending moment capability of such an interface. Thanks to the innovative technology and unique design (patented), the adaptive clutch maintains its maximum stiffness in the idle mode of its passive operation. Then it switches to the compliant mode within few milliseconds, completely changing the way loads are transferred through the interface, which means ca. 50 times lower load levels than in the idle mode. The adaptive clutch can bear quite significant moments (ca. 50 Nm) relatively to its compact external dimensions (ca. 10 cm). The dimensions of the adaptive clutch can be both downsized or upsized depending on the application.
Main parameters of an adaptive clutch, elaborated for demonstration, are the following:
- height 78 mm,
- outer diameter 88 mm,
- weight 1,8 kg,
- max. moment 50 Nm,
- min. moment 1 Nm,
- actuation voltage 0-150 V.
Main advantages of the adaptive clutch:
- high transferred moment compared to compact design,
- fast reaction time,
- fail safe operation.
- efficient semi-active vibration attenuation along with PA–R System,
- controllable voltage-driven clutch,
- structural joint of variable bending moment capability,
- structural fuse.
Portable weigh-in-motion rail device
Portable weigh-in-motion rail device is prepared for identification of parameters of loads exerted on the railway track by moving vehicles. The system developed by Adaptronica allows for weighing trains in motion.
Portable weigh-in-motion rail device makes use of the measurement of rail strain caused by the passing train. The device uses portable transducers (patented), attached to the rail foot in a non-destructive manner. The main components of the measurement system are schematically presented in Fig. 1.
The characteristic feature is that the additional preparation of the ballast and sleeper before the system installation is not required. The installation process of the detectors is fast. Closing the railway line is not necessary.
An important advantage of the system is the use of portable detector mounted on the rail foot by clamping elements, which significantly reduces the installation time and cost. The clamping element is designed in such a way that it can be adjusted to all types of rails. Before installation, additional preparation of the track is not required e.g. hardening of the ballast. A view of the portable weigh-in-motion rail device is presented in Fig. 2.

Recorder of touch-down parameters - AVI
System AVI of measurement and recording of the touch-down process, elaborated by Adaptronica performs the measurement of vertical speed of an aircraft and its distance from runway during touch-down. The system enables the user to assess the loads acting on the aircraft structure during landing.
The measurement of vertical speed of the aircraft and its distance from runway utilizes a transmitting-receiving ultrasonic head as well as targeted aquisition and signal analysis. The transmitting-receiving head allows for improving the ratio of the analyzed signal to noise level generated by the aircraft in flight.
The level of loads acting on the aicraft structure during touch-down is measured by an accelerometer placed in a preselected spot on the aircraft.
Thanks to aquisition and storage of measurement data on SD card, the system AVI provides better assessment of pilot skills based on recording of the touch-down process. It also enables monitoring of structural fatigue.
AVI can be applied on ultralight and light aircrafts and can be also adapted for unmanned aicraft vehicles.
The advantages of the AVI system are the following:
- possibility of assessment of pilot skills based on recording of the touch-down process,
- better evaluation of structural fatigue due to repetitive loads,
- possibility of assessment of aircraft failures,
- storage of data on SD card,
- waterproof ultrasonic head,
- autonomous power supply,
- low power demand,
- compact dimensions and low mass,
- easy mounting.
The main application of the vibration recorder is to take and store measurements of vibrations occurring in heavy-duty constructions and installations during their exploitation. The device elaborated by Adaptronica sp. z o.o. allows for taking measurements in harsh ambient conditions. The vibration recorder is equipped with a 3-axial accelerometer merged with an accompanying cable, which facilitates the installation. The acquired data with proper time signature are stored on SD card of maximum capacity 32 GB. The recorder can be powered through dedicated power supply or through batteries.

Structural health monitoring
Adaptronica offers systems for condition monitoring of engineering structures such as bridges, viaducts, towers, warehouses. The company has developed and installed customized systems which perform measurements, recordings, signal analysis and remote transmission of data. The purpose of the system is to monitor the condition of a structure by examining quantities like acceleration, deflection, strain, angle of inclination as well as environmental parameters such as temperature, humidity and atmospheric pressure. The system provides both local storage of the measured signals for archiving purposes but also on-line, remote viewing of parameters processed in the analysis. In order to increase the reliability of the systems, Adaptronica utilizes hardware by renowned world brands such as Bruel & Kjaer or National Instruments. Depending on the needs and expectations of the client, systems are always configured individually.
An example of a system, implemented by Adaptronica on an engineering structure is the system for monitoring of acceleration levels on suspension rods of the railway viaduct in Huta Zawadzka (Fig. 1 above). Bruel & Kjaer transducers, National Instruments controller and measurement cards, and Telium wireless transmission module were used.
The following parameters of the measurement system were adopted:
- frequency range of the recorded acceleration 0.5-100 Hz,
- amplitude range of the recorded acceleration ± 5 g,
- acceleration measurements in three directions,
- temperature and humidity measurements,
- wireless transmission of data,
- emergency power supply up to 12 hours.
Sensors were mounted in a non-invasive way on some suspension rods of the bridge. In order to obtain the degree of environmental protection IP65 for the measurement system, the cables were placed in protective coatings and the sensors were located in hermetic housings.
Measured acceleration signals were stored in the local memory of the system for one month. Every five minutes, the selected measurement results, such as the maximum and average (RMS) values, were sent to the server.
The user interface designed for the system (Fig. 2 above) is capable of:
- viewing the history of measurement signals in both the time and frequency domain,
- tracking changes in monitored parameters,
- studying correlations between mechanical quantities and environmental values,
- controlling the system.
