    The use of a state-estimator is a more practical way of developing active controllers. In this paper we investigate two control methods using state-estimators. We also use simple models of disturbances to test attenuation and robustness of each control method. One of the earliest programs to develop a quiet aircraft led t o a five-bladed prop test bed with extensive muffling; the aircraft was extremely quiet but was far too heavy t o be effi-cient. In the NASA Acoustics Division was organized and in- 5/5(3).

An aircraft-based, imaging probe is being proposed for the reliable and accurate measurement of liquid water content (LWC) and droplet size distributions in environments variously referred to as freezing rain, freezing drizzle, supercooled drizzle drops, and supercooled large drops (SLD).

Given that a large test might use more than In order to achieve the project objectives, we plan to carry out the following tasks in Phase I: (i) Modify F/A aircraft simulation to test the feasibility of the proposed approach; (ii) Develop the IHM-FLARE architecture and algorithms; and (iii) Evaluate the performance of the flight control system under false failure information.

PALS was designed and built to investigate the benefits of combining passive and active microwave sensors for Ocean salinity and Soil moisture remote sensing. It is the prototype for the Aquarius and SMAP missions and its flexible design is compatible with many aircraft. According to Yan et al.

(), UAS are considered as the full system, including the aircraft, the remote control station and all of the ground support elements, communication links, air traffic control, and launching and recovery system, as may be required (this is the opinion of the Civil Aviation by: The SMMR performance for atmospheric water content has been analyzed in terms of columnar water vapor and liquid water content and rain rate.

Only columnar water vapor is illustrated here based on the frozen-orbit data sets which provided radiosonde observations (raobs) deployed from Funafuti, Majuro, Kwajalein, Wake Island, Truk, Ponape, and Cited by: 1. The first two more prototype aircraft produced and every conceivable maneuver-for the runways constructed were each however, to produce the proper drop size and liquid water content with the available water dispensing systems.

Develop such systems for prototype demonstration and field testing on mobile platforms such as motor vehicles and drones.

Enhanced 3D imaging capabilities can be explored with enhanced range and resolution based on coherent imaging.

Generally the supercooled liquid water content is fairly low. The ships would spray seawater into the air to enhance cloud reflectivity.[6][7] A prototype Rotor ship was tested on Discovery Project Earth.

The rotors were made of carbon fibre and were attached to a retrofitted trimaran and successfully propelled the vessel stably through the water at a speed of six knots. The most significant difference between these two airfoils was the NACA more sensitivity than NACA to liquid water content (LWC).

We believe that the results showed in this paper will be useful for the designer of the commercial aircrafts and UAVs, and will be helpful for training of the pilots to control the airplanes in heavy rain. PHASE II: Develop prototype software to demonstrate and test the feasibility and effects of proximity-based access control.

(Consultant to Department of Atmospheric Science, Colorado State University Fort Collins, CO) ABSTRACT This paper discusses the technology required to generate clouds of sub-micron size carbon particles and disperse them directly into the air from airborne, ground, or sea surface sources for use in large-scale weather modification experiments.

Test crews found their encounters with highaltitude gusts at supersonic speeds more objectionable than their exposure to low-altitude gusts at subsonic speeds, even though the given g-loading accelerations caused by gusts were less than those experienced on conventional jet airliners At the other extreme of aircraft performance, inthe.

While research aircraft can collect comprehensive microphysical and radiative data in clouds, the duration of these aircraft is relatively short (up to about 12 hours). During the course more» of the Phase II research, a tethered balloon system was developed that supports miniaturized meteorological, microphysical and radiation sensors that.

A robust theoretical foundation and convincing evidence constrain the forcing caused by aerosol-driven increases in liquid cloud droplet number concentration. However, the influence of anthropogenic aerosols on cloud liquid water content and cloud fraction is less clear, and the influence on mixed-phase and ice clouds remains poorly constrained.

A prototype instrument to measure freezing and moisture characteristics of porous media was developed. The prototype is being modified for commercial production now. Also at WSU, a comprehensive review was completed on the use of dye tracers for vadose zone hydrology (Flury and Wai, ).
