Intro to motor constants for fractional horsepower gearmotors

According to motor expert Bodine Electric, "Motor constants are needed to calculate permanent magnet DC (PMDC) or brushless DC (BLDC or EC) motor specifications and ratings, or to match the motor properly to an amplifier." You need the constants to predict the motor's performance with changing variables, such as different input voltages or different loads. This app note explains what the constants are, how they are derived. and how to use them. Very useful.

Airbus achieves world's first fully automatic air-to-air refueling contacts with fighter jet

Airbus tanker test aircraft equipped with the Airbus A3R solution supplies an F-16 fighter aircraft of the Portuguese Air Force.

 

 

Airbus has achieved the first-ever fully automatic air-to-air refueling (A3R) operation with a boom system. The flight test project, conducted earlier in the year over the Atlantic Ocean, involved an Airbus tanker test aircraft equipped with the Airbus A3R solution, with an F-16 fighter aircraft of the Portuguese Air Force acting as a receiver.

During initial approach of the receiver, boom control is performed by the tanker's Air Refueling Operator (ARO) as usual. Innovative passive techniques such as image processing are then used to determine the receiver's refueling receptacle position. When the automated system is activated, a fully automated flight control system flies and maintains the boom aligned with the receiver's receptacle. The telescopic beam inside the boom can be controlled in a range of ways, including: manually by the ARO; a relative distance-keeping mode; or full auto-mode to perform the contact.

Once the system is activated by the ARO, the A3R flies the boom automatically and keeps the alignment between the boom tip and the receiver receptacle with an accuracy of a couple of centimeters; the proper alignment and the receiver stability is checked in real time to keep a safe distance between the boom and the receiver and also to determine the optimum moment to extend the telescopic beam to achieve the connection with the receiver.

At this point, the fuel transfer is initiated to fill up the receiver aircraft. Once completed, the disconnection is commanded. The boom is then cleared away from the receiver by retracting the telescopic beam and flying the boom away to keep a safe separation distance. During this process, the ARO simply monitors the operation.

This milestone is part of the industrialization phase of A3R systems ahead of its implementation in the A330 MRTT tanker development.

The campaign achieved a total of 45 flight test hours and 120 dry contacts with the A3R system, covering the whole aerial refueling envelope, as the F-16 and MRTT consolidate the maturity and capabilities of the development at this stage. The certification phase will start in 2021.

The A3R system requires no additional equipment on the receiver aircraft and is intended to reduce air refueling operator workload, improve safety, and optimize the rate of air-to-air refueling transfer in operational conditions, helping maximize aerial superiority. The goal for the A3R system is to develop technologies that will reach fully autonomous capabilities.

David Piatti, who acted as Airbus Test ARO (or "boomer") on one of the A310 tests, said, "It was extremely impressive to see how accurately the A3R system tracks the receiver. It can be very useful to be able to refuel another tanker or transport, for example to extend its deployment range or to avoid taking fuel back to base, but it is also a challenging operation and this system has the potential to reduce workload and the risk involved."
