This paper presents the results of theoretical and experimental research of a prototype of a propulsion system for periodical low-Earth orbit correction of research-and-educational nanosatellites. For that purpose, the prototype is to provide at least 20 m/s relative velocity for a 3U CubeSat with a mass not exceeding 4.5 kg. The personnel and environment safety were taken into account during testing and operation along with the ability to be launched as an associated payload by a “Soyuz”-series launch vehicle or from the ISS. An electro-thermal propulsion system (ResistoJet) was designed with “nonfreezing” mixture of ethanol and distilled water used as the working fluid. It is shown that a standard vehicle power system is capable of initiating one corrective thrust impulse per orbit with flight velocity change of about 0.1 m/s by introducing pulse energy storage units and allocating sufficient time for their charging in the flight profile. The propulsion system prototype was tested in atmospheric conditions. For that purpose shortened “atmospheric” nozzles were used. Testing was carried out using a zero-torque test-bench with high-speed cameras. The measured thrust value was in agreement with the calculated value of 44 mN.

A solid propellant microthruster array consists of three parts (five layers) was designed to form propulsion system of nanosatellite. The layers of the array were fabricated by different MEMS technique respectively. Then the array was assembled by adhesive bonding (H70E thermal epoxy). An initial test was operated with the ignition test stand composed of high speed video system, electronic power source, and oscilloscope. A constant voltage was applied to the igniters through two probes contact with the pad of ignition circuitry. The test indicates that the microthruster array can be ignited under 15V.

In order to realize propulsion system and oxygen system of tourist submarines be secure, eco-friendly, efficient, reliable, economical, a combination of ordinary air motor and ACM high-pressure air bottle is adopted for providing propulsion and oxygen. The calculation and selection of the appropriate air motor and high-pressure bottle are based on the propulsive requirement of a tourist submarine. A model consists of high-pressure bottle, air motor, propeller and the resistance of the tourist submarine is established in SimulationX. The underwater speed and it’s duration are obtained through calculation as the rev, thrust force, torque of the propeller, etc. The possibility of application of pneumatic propulsion method in tourist submarine is analysed. Results illustrate that: on the premise of lightened quality of the propulsion system, pneumatic propulsion method fulfills the required underwater speed and it’s duration.

A representative subsonic V/STOL aircraft operating on a single mission has been used as a baseline to investigate the impact of various propulsion system tradeoffs. After establishing a cycle for the propulsion system and estimating V/STOL related installation penalties, parametric engine-aircraft-mission studies have been conducted. These studies have established takeoff gross weight benefits of up to 13 percent that may be obtained by appropriate selection of the core engine sizing location. Studies of two, three and four engine versions of the configuration have shown that three engine and four engine aircraft may have 20 percent lower weight than a two engine version, but this arises at the cost of significantly reduced hot section life.

The design of the propulsion system for Unmanned Aerial Vehicles (UAVs) demands an inclusive multidisciplinary approach from the earliest design phases, since every design choice strictly affects and is affected by the overall working conditions. This paper presents a review of the scientific literature focused on the design methods applied in defining and sizing the propulsion system of drones. The analysis, performed with a systematic approach, evaluated 123 papers according to two custom classification taxonomies, which investigated respectively the primary aim and specific content of the works. Finally, literature indications and hints were combined into an integrated framework for the functional design of the propulsion system of UAVs. The procedure aimed to support the designer in the preliminary selection of the propulsion candidates and the quick sizing of the supply system, during the first phases of the design process. According to the literature, design methods dramatically change depending on the expected applications and working conditions of UAVs, so that the detailed design of specific drone elements and propulsion components represents the focus of most of the papers in this field.

India is one of the prominent manufacturers in the automobile industry with 30 Million of vehicles production rate. Most of vehicles manufactured in India utilize internal combustion power drive methodology. Additionally, pollutions, global warming, conventional fuels exhaustion and loss of building materials are the major concerns associated with IC engine technology. Electric drive technology has the potential to mitigate these issues. Three-wheeled (3-W) battery powered rickshaws/vehicles are primarily employed for public conveyance in the metropolitan cities of India. The motor (propulsion) is a vital component of 3-W battery powered rickshaw. But, selection of appropriate propulsion system for 3-W rickshaw is crucial step. In the present study, an exertion has been prepared to assess the correct propulsion system for 3-W battery powered vehicle in Indian contest.
