舰载直升机悬停操纵特性影响较大，而侧向分量影响较小。文中着重建立适于工程应用
的甲板流场计算简化方法，以用来方便地确定甲板流场和无人直升机着舰时的操纵需求，也
可用于舰载直升机起降包络线计算来指导舰载直升机飞行训练。

Abstract An NS equation with
finite element method is used to
simulate the flow field over
the flight deck of a middlesized ship, and th
en the flow field is added
to mathematical model of an unmanned helicopter. How
to simplify the calculation
of the flow field and how much affection of the wake
on the helicopter trim when
it is hovering over the deck are specially invest
igated, excluding the interface
between rotor wake and board wake. It is a simp
le model for helicopter/ship
dynamics. The vertical component of the flow has a
very important effect on the
helicopter, while the horizontal component is i
gnored. The result may be used
in flight training and in deciding the control
requirement of an unmanned
helicopter hovering over the flight deck, and
also in the design of the control
law for an unmanned helicopter during taking o
ff and landing.

Abstract An attack helicopter
is one kind of the most powerful
weapons in modern warfare.
For the operational effectiveness analysis of weapon
sy
stems, combat simulation plays
a significant role against other methods. The mat
hematical model for a helicopter
attacking a ground target under hostile threat
environment has been established
by using Markov process. Then the effectiveness
expressions, such as the probability
of mission success, the probability of kil
led target and the probability
of helicopter loss during the attacking mission
are presented, as well as their
calculations. The relationship of costeffectiv
eness and the optimal operating
time for an attack helicopter are discussed. Th
e influence of refitting airborne
electronic countermeasure devices upon the ope
ration effectiveness is demonstrated
with a specific example.

Abstract It is known that some
level of entrained air in fluids
is inevitable. The air presented
in the form of bubbles makes the fluid in d
ampers compressible obviously.
A mathematical model is developed to descri
be the
hydraulic damper′s property
with compressible fluids. The varying bulk modulus
is introduced into the pressure
differential equation. Numerical simulation is
compared with the experiments
for the landing gear shimmy damper of K8 aircraft
. The experiments include the
case in which the fluids in the damper are insuff
icient, that is some amount
of free air is contained in the damper. The research
indicates
that the compressibility affect
the property of hydraulic dampers. The ef
fect of air percentage, amplitude
and frequency of exciting vibration
upon the damping property
is also discussed.

Abstract A theoretical and

(SEP) made of fibrous stainless steel is
presented. The experimental
results show that the SEP is more efficient than a
tubularEP and other existing
sack precipitators. It draws a con
clusion that SEP is better
in collecting slight particles than tubularEP and s
ack precipitators. The curves
of efficie

y versus filtering velocity,
voltage and dust consistency indicate how these pri
mar
y parameters influence the
efficiency of the SEP. Therefore, the SEP may be used
as a extensively dust trap
for steel making electricfurnaces and some other

is helpful to research electrostatic precipitator and

Abstract In order to avoid
deflective load which may affect the
strength and dynamic performances
of a face gear, the face gear drives chiefly
adopts spur gear whose
tooth number is less than that
of shaper so as to achieve point contact transmis
sion. This paper has given
the gear surface equation and meshing contact poin
t equation in face gear drive.
A program is developed to simulate the contact po
int tr
ack. The influence of main
transmission factors on contact point position is ana
lysed and some rules used in
engineering are obtained. The gear tooth difference
,tooth number ratio and modulus
have great effects on the engaged contact point.
If the tooth difference has
been increased or tooth number ratio or modulus de
creased, the contact point
will move toward the small end of the face gear.

Abstract In rotating platform
imaging in microwave anechoic cham

the rotating angle in order to obtain high r

angle results in out of focus of the obtained
image. This paper deals with
the imaging method of modeling radar echo da
ta of an object on a rotating
platform with panel method in the case of large ro
tating angles. The echo data
are directly calculated in Cartesian coordinate sys
t
em of spatial frequency and
processed with twodimensional fast Fourier transfo
rm (2DFFT) to obtain the image
of the object. By simulation, it is shown that
the quality of the resulting
image is much better than that of the image obtaine

Abstract The establishment
of agent model is an important topic
in the current research of
agent theory. One of the main works to establish an a
gent model is how to model
the mental states of an agent，the constraint relatio
ns of the mental states and
the affection between the mental states and the acti
on of the agent。In this paper，an
agent model is constructed which has the
advantages of BDI model and
the situation calculus. In the agent model，the me
ntal states of an agent are
comprised of state beliefs,effect rules,feasibility
rules,strategy rules and intentions.
At the same time，if the mental states of
the agent are complete information
and a situation variable is added to each flu
ent，then it becomes an action
theory based on situation calculus proposed by R
eiter. Therefore, the agent
model described above can not only represent the men
tal states of the agent，but
also reason about action and plan. Finally，a run m
anner of the agent to implement
its goal is proposed if the mental states of the
agent ar
e information complete.

Abstract Sensors on an aircraft
are easy to lose effectivene
ss if the aircraft flies at
low altitude and there are many obstacles on the fli
ghtroute. Aiming at this fact,
this paper suggests that the multisen
sor system must take effective
information fusion measure in the course of penet
ration at low altitude, studies
the fault tolerance problem, and proposes an al
gorithm about the fault detection
and isolation at the sensor level, through whi
ch the ineffectual sensors
are easily rejected and the systems pollution degree
is reduced. Then, a simple
and useful information f
usion algorithm is given, which
can parallelly process the data from each effect
ive sensor, and there is no
need to communicate among local processors. Less da
ta need to be stored in these
processors, thus the realtime processing capaci
ty of the system is improved.
Finally, the theoretical analysis is proved by an
example.

摘要 K8教练飞机设计中的颤振分析包括数值计算、风洞试验
、地面试验和飞行试验等工作。这些工作是在飞机设计和制造的不同阶段进行的，且彼此相
关密不可分。文中对每一项
工作作了评述。指出若仅采用其中的某一项分析或试验表明飞机的颤振特性尚有不充分之
处。只有将各种分析和试验结果进行相互验证、比较和修正，并进行综合分析，才能得出
该飞机颤振安全的正确结论。

Abstract An important part
is played in the reliabilitycentere

for their alert value (or upper control li

the UCL based on the failure se
quence analysis is presented.
The method is suitable for many components or sys
tems, of which the failure
rate is cyclically fluctuated due to the weather and
the environment. Some real
data obtained from an airli
ne company are employed and
then analyzed by using this method, and it is shown
tha
t this method is satisfactory
for the analysis of cyclic failure data. The more
accurate forecast will be achieved
for larger failure data and longer duration.
