Opis:: The engine-compressors GMVH types are used in the national gas transmission system in Poland. There is a danger of scuffing of the working components of the engine-compressor particular pistons and cylinders during the process of their exploitation. The growth of resistance in motion parts of the machine is the main symptom of the scuffing. In the cinematic system of the engine-compressor where the engine and compressor are fully mechanically integrated it is impossible to assess the power of mechanical friction without stopping the machine. But if the engine-compressor is equipped with a cylinder pressure measuring system it is possible to determine the indicated power of all compressor and engine cylinders and assess the friction losses as a difference between the sum of the engine 's cylinder s indicated power and the sum of the compressor's cylinders indicated power. In the differential measurements of absolute values measuring errors are accumulated so considerable uncertainty of the measured parameter is expected. The accuracy of the friction power losses assessment method is not sufficient for research purposes. However, despite the expected significant errors, assessed parameters trends observation should allow to detect ofrapid changes of machine technical condition caused by piton scuffing. To ensure the sense of this method a precise measurements and in particular the error consistency of indicated pressure assessment of all cylinders in long time period are necessary. The experience from engine-compressors monitoring and diagnostic system services, the main sources of errors and methods for their minimization are described in the paper.

Opis:: The paper is focusing on selected problems of health monitoring of tall type buildings. The actual problem in structural health monitoring (SHM) is to find the damages and its location by performing some statistical pattern recognition based on the measured data termed as feature extraction. The damage caused by environmental loads should be repaired; otherwise, it will expand with time and might lead to complete system failure. Dynamic parameters, such as velocity, acceleration and displacement, play a significant role in determining the structure dynamics. This paper is focusing on smart wireless sensors application into health monitoring systems of tall type buildings operating into hazardous environment and selected methods for data analysis obtained from the monitoring system. Smart sensors can locally process measured data and transmit only the significant information via wireless communication. As a network, wireless sensors extend the capability. Significant future developments of smart wireless sensors technology in tall type buildings in hazardous environment come by way of multi-disciplinary research efforts encompassing fields such as data analysing, signal processing, structural dynamics, motion and environmental sensing hardware, computational hardware, smart materials, data telemetry and statistical pattern recognition, as well as other fields yet to be defined. Specification issues that require automation of the decision making process in the evaluation of the technical state of the tall type structure have been also discussed.

Opis:: The article discusses the examples of fire causes in the military vehicles and the consequences they may cause in the military vehicles. It has been observed that the frequent cause for the damage of military vehicles and loss of crew health and life is not the direct impact with the missile, but fires caused e.g. by impact with a missile, mines and firing bottles actions. Therefore, there is the need to use firefighting systems in the military vehicles. The development of the firefighting systems earmarked for the military vehicles has been presented. The contemporary construction solutions for the firefighting system earmarked for the motor and combat departments, as well as selected external parts of the military vehicles as well as basic conditions influencing the firefighting systems of various purposed have been discussed. The advantages and disadvantages of halons used previously as basic extinguishing means, current legal restriction concerning the halon use as well as potential halon equivalents to extinguish fires in the military vehicles have been discussed. The new extinguishing equipment, the means of which will not have negative impact on the crew, vehicle and natural environment – in particular in terms of destroying ozone layer and causing greenhouse effect will require checking the correctness of their functioning, the extinguishing effectiveness and the impact on the natural environment. The testing of the firefighting systems for military vehicles has been already conduced in the Military Institute of Armoured and Automotive Technology in Sulejówek.

Opis:: The paper analyzes the factors influencing the quantity and quality of diagnostic information obtained by engine indication with electronic indicators and pressures analyzers. Amount of information obtained virtually unchanged since the advent of the first construction pressure analyzers produced by Autronica and ABB Company. In many cases, the value of the maximum combustion and compression pressures, can be measured using these devices with sufficient accuracy and reliability, is if ignition occurs after piston TDC. Determination of the mean indicated pressure, compression ratio and heat release characteristics required to develop a method of TDC determination on the indicator diagrams, generate reliable angular axes in real time and pressure sensors of sufficient accuracy. It should be noted that in the latest solution of ABB system, a correction of thermodynamic loss angle and combustion pressure sensors of high accuracy were introduced. For marine diesel engines diagnosis, the pressure sensor measuring sustainability is important because of the ability to create trends of specific diagnostic parameters, which may constitute an additional, important source of diagnostic information. The paper presents an overview of currently available pressure sensors that can be used during marine engines indication. Most important issues related to the pressure measurement on indicator valves were characterized. An assessment of the gas channels and the quality of the angular axis impact for the parameters of indicator graphs was done.

Opis:: The presented article is devoted to the problem of detection and localization of damages occurring in components of structures, which are made of hybrid composite materials. The subject of the work is a square plate consisting of a single layer made of aluminum alloy and several layers made of glass fibres (glass fabric) and epoxy resin. On the surface, which is made of composite, 12 piezoelectric elements are installed. These elements sequentially, one by one, generates a signal that is further recorded by the remaining piezoelectric elements. Picked up signal for the selected pair of activator – sensor is compared with the reference signal. The reference signal corresponds to the intact structure. This kind of approach is known as the pitch – catch configuration. In situations when the signal obtained for interrogated structure and reference one differs significantly, this may indicate that a damage exists between the activator and the sensor. Next, taking into account the information obtained from the other sensors, it is possible not only to detect but also to determine the approximate location of the flaw and to estimate its size. In order to visualize the obtained results, an especially dedicated software is developed according to the algorithms available in the literature – probability ellipse. Several computer simulations of wave propagation are performed using the finite element method. The proposed procedure is also tested experimentally. The presented approach makes it possible to detect both single and multiple damages.

Opis:: Provision of well-being in rooms is associated with their good ventilation. Good ventilation is influenced by cleanliness of ventilation ducts. The article presents a drive-by-wire version of a mobile inspection robot for ventilation ducts. A handler, which is movable in three axes and ended with a grab, a supporting vertical wheel (to reduce wheel skid) as well as a colour camera, a distance sensor and two light sources (LED and halogen lamp) on a rotary platform have been placed on a circular chassis. Apart from performing the inspection function, the operator of the "Inspector 1" robot may remove bigger pieces of dirt and garbage from a ventilation shaft using the handler and the grab. The device is powered from a 12 V / 5 Ah battery. A robot controlled using a control panel allows accurate illumination of the internal walls of the duct and wireless transmission of a colour image to the operator's monitor. The rotary platform on which the camera with lighting is placed is also capable of tilting up and down. The robot's drive has been resolved in a way that makes it as manoeuvrable as possible. Two front drive wheels operate independently and two rear wheels are easy-running. The robot will also allow recording the following environmental parameters in the ventilation shaft: humidity, temperature, draught force and direction and the presence of gases. The entire robot's electronic system is based on battery-powered supply (12V/5Ah) which is sufficient for approx. two hours of continuous operation. The voltage of the battery is constantly monitored and should it drop.
