NASA will create a program for design drones
The new program will allow you to simulate flight tests of the devices.
NASA experts intend to in the next six months to complete the development of new software, which will allow to simplify and automate the design of unmanned multicopters and electric mnogolistovyh piloted vehicles.

Drones against the law: what you need to know when buying a drone
As written by Aviation Week, a project called Deliver. Largely it is based on an existing software NDARC (NASA Design and Analysis of Rotorcraft, the design and analysis of helicopters NASA), is intended for the design of rotorcraft technology.
The existing systems of the automated designing allow you to create a digital model of a prospective aircraft, and then to calculate its aerodynamic properties, simulate the behavior in the air flow, to predict the performance of individual nodes and to determine the level of noise that such a device will produce.
If it does not yet exist a specialized computer aided design that is optimized specifically for developing multi-rotors.
Multicopter, manned or unmanned, produce a lot of air flow, which can be mixed with each other, creating a zone of high turbulence. If you don’t consider the possible consequences of the mixing of flows from the mutual influence of the rotors on the effectiveness of each other, to create a reliable flying machine will fail: he will either be unstable in flight, or will consume more energy than necessary.

The new software will allow NASA to create a digital model of multicopter, and then performed a few basic calculations. In particular, the system will Deliver enable to simulate flight tests of the new mnogolistovyh techniques that will allow to abandon the full-scale flight tests. With the new program, designers will be able to predict the noise level that will produce a quadcopter in flight. Finally, Deliver will allow you to scale a digital model, facilitating the creation mnogolistovyh equipment of different sizes.
In mid-may of the current year the Management of research projects in the field of Aeronautics, NASA has launched a crowdsourcing campaign aimed at the significant acceleration of the hydrodynamic calculations for advanced aircraft. The campaign opened on the grounds of Topcoder and HeroX. Planned to be completed on 29 June 2017. The winner or winners will receive a prize of 55 thousand dollars.
The purpose of crowdsourcing campaigns is the development of the software FUN3D or used by algorithms so that the hydrodynamic calculations were performed on the Pleiades supercomputer of the NASA faster, from ten to ten thousand times. The ideal result would be considered if between the input data and obtaining the calculations will take place not more than a day.
